5.3. View and Save Simulation Statistics

You view and save simulation statistics either after you have finished processing a simulation or have completed enough of the processing that the data you want to analyze is available.

You can use the data directly on the Properties and Curve tabs to view an individual statistic for a property; or you can graph an entire data set by creating plots and histograms, or by exporting the data you want to a CSV file to view from a spreadsheet program, such as Microsoft Excel.

5.3.1.1. About Viewing an Individual Statistic

The steps you take to view an individual statistic depend upon whether the property you are interested in has been calculated yet. Sometimes Rocky calculates other individual statistics with the statistic you have chosen if doing so will save on calculation time.

5.3.1.1.1. Identifying Whether or Not Data Has Been Calculated

You will know whether a property has been calculated or not by what operational values (Min, Max, and so on) are displayed in the panel tab, as explained below and illustrated in Figure 5.79: Property column header options in the Data Editors panel:

  • If you see question marks <?> or <unknown> in the property row, the data has not yet been calculated.

  • If you see values <numbers> in the property row, the data has already been calculated.

  • If you see -1.#IND in the property row, the calculation is invalid for that particular timestep. This can happen if there is no particle in the simulation at the time selected, for example.

(See also Recognize Data Placeholders.)

5.3.1.1.2. About Viewing Already Calculated Statistics

For properties that are already calculated, viewing an individual statistic involves either hovering over the property and viewing the information in the tooltip, or customizing the column headers for the panel tab so that the values you want to view are visible in the UI.

5.3.1.1.3. About Viewing Not Yet Calculated Statistics

For functions that have yet to be calculated, viewing an individual statistic involves first choosing to Compute Statistics, which is affected by how frequently you have chosen calculations to be updated. (See also Determine the Frequency of Calculations by Pinning/Unpinning Items.) The results of the calculation are dependent upon what kind of data item you chose, as described below:

  • For items on the Properties tab, choosing to Compute Statistics results in only the current timestep being calculated for the function chosen.

  • For items on the Curves tab, choosing to Compute Statistics results in all currently available timesteps being calculated for the property chosen. But unlike pinning an item, choosing to Compute Statistics will not continue to recalculate those values should settings change that affect them, nor if new timesteps are added to the simulation.

5.3.1.1.4. Column Options for Property and Curve Rows

Use the image and table below to help you understand how you can view an individual statistic in the Rocky UI.

Max

The highest value of all the recorded data for the property or curve.

Sum

The final value when of all the recorded data for the property or curve are added together.

Sum Squared

The final value when of all the recorded data for the property or curve are added together and squared.

Average

The average value of all the recorded data for the property or curve.

Variance

The variance between of all the recorded data for the property or curve.

Std. Deviation

The standard deviation between of all the recorded data for the property or curve.

Unit

The unit used by the value.

Type

For Properties only, indicates the underlying data type storing the value.

Location

For Properties only, indicates the specific part of the entity to which the property is applied. For example:

  • Cell is equal to one value per geometry triangle.

  • Node is equal to one value per triangle vertex.

Evaluation

For Properties only, defines whether the property is "Instantaneous" or "Statistical". Specifically:

  • Instantaneous properties are the values that the entity had at the moment the output file was written. These most often indicate "standard" properties that are provided in Rocky by default.

  • Statistical properties are the result of some kind of computation over the values between two consecutive output files. These most often indicate that data collection had to be turned on prior to processing the simulation, as with collision statistics. (See also About Collision Statistics for Boundaries.)

  1. Use the Time toolbar to select the exact point in the simulation for which you want information. (See also About the Time Toolbar.)

  2. From the Data panel, select the entity containing the property for which you want to view an individual statistic. This can include a conveyor or imported geometry component, Particles, 1-Way LBM, 1-Way Fluent, Solver, or any individual User Processes linked to these entities. (See also Use Properties and Curves.)

  3. From the Data Editors panel, select either the Properties or Curves tab containing the property for which you want to view an individual statistic.

  4. Do one or both of the following:

    • If the information has yet to be calculated (e.g., the values show question marks <?> or <unknown>), right click the property you want, and then click Compute Statistics. The values for the selected timestep and property are displayed on the tab.

    • If the information has already been calculated, display the information in one of the following ways:

      • In a row of the panel tab by right-clicking the header row for the property table, and then left-clicking the values you want shown/hidden from the menu displayed.

      • From a tooltip by hovering your mouse over the property.

5.3.2. Graph (Plot or Histogram) a Data Set Within Rocky

In Rocky, you create plots—such as Time Plots or Cross Plots—and histograms when you want to see a graphical comparison of various data sets in the UI.

After selecting your data and displaying it in the plot or histogram window of your choice, you can then modify your graph by changing the window and data properties of your choosing.

What would you like to do?

See Also:

5.3.2.1. Graphing (Plot or Histogram) a Data Set Within Rocky

In Rocky, there are five different types of graphs you can create with your simulation data, as described below:

  • Time Plot: Graphs data across a time period. Also enables you to inspect a particular point in a curve and see the results in table format.

  • Multi Time Plot: Like a Time Plot, graphs data across a time period but enables multiple plots to be compared in one window.

  • Histogram: Provides a graphical representation of the distribution of a data set. It represents in vertical bars the data set previously tabulated and divided into uniform bins. The base of each bar represents a class and the height of each bar represents the amount or frequency with which the value of the class occurred in the data set.

  • Space Plot: Graphs one-dimensional (line) data from the Properties tab.

  • Cross Plot: Displays in a dot-cloud format correlations between two entity properties (Curves or Properties) that share a common domain.

Creating one of these graphs produces a window within the Rocky workspace that you can then drag and drop a Property or a Curves data set into (see also Use Properties and Curves.). From there, you may use the options on the Window Editors panel to change the appearance of your graph, including settings like background color, font color/sizes, axis and legend information.

For Histograms only, you can also determine by which method you want the data weighted through the Configure Histogram dialog. This also enables you to change the number of bins, and whether the data is aggregated by percentage and/or by cumulative methods.

For Time Plots and Multi Time Plots only, you can also add an Annotation, which places a mark and caption in a location of your choice on the graph. (See also About Creating an Annotation on a Time Plot or Multi Time Plot.)

Once your graph contains the data you want and appears the way you prefer, you may then choose to save the graph as an image or export it to an external CSV file (see also About Exporting Data Out of Rocky.)

5.3.2.1.1. About Time Plots

A Time Plot graphs data across a time period (Figure 5.80: Example Time Plot). Like any other Plot in Rocky, you can inspect a particular point in a curve or zoom-in on a particular area (Figure 5.81: Inspecting a Time Plot Curve with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)). Unlike Multi Time Plots, which accepts many sub-plots in one window, Time Plot windows accept only one plot at a time. However, Time Plots are the only graphs within Rocky with the ability to view and add custom formulas to the results in table format (Figure 5.82: Table tab results of the example Time Plot).

5.3.2.1.1.1. About the Plot tab

Inspecting a Time Plot Curve with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)

The Plot tab of a Time Plot window is where the graph itself is located. As with Multi Time Plots, you can add an Annotation or a Time Mark to a Time Plot. An Annotation places a mark and caption in a location of your choice on the graph (see also About Creating an Annotation on a Time Plot or Multi Time Plot) while a Time Mark enables you to identify with a vertical line the location of the Current Timestep.


Tip:  To see walk-through examples of Time Plots being used to analyze simulation results, refer to the following Tutorials:


5.3.2.1.1.2. About the Table tab

The Table tab for a Time Plot (Figure 5.82: Table tab results of the example Time Plot) enables you to view the data in tabular format and also add and edit custom formulas using variables and expressions (see also Defining Your Variables) that will themselves be calculated and added to the graph.

See the images and tables below to understand how you can use the options on the Table tab for a Time Plot window to change the data displayed in your graph.

5.3.2.1.2. About Multi Time Plots

A Multi Time Plot is a type of graph that like a Time Plot, graphs data across a time period while also enabling you to inspect a particular point in a curve or zoom-in on a particular area (as shown below). But unlike a Time Plot, a Multi Time Plot enables multiple plots, called sub-plots, to be compared in one graphical window:

Figure 5.85: Inspecting a Multi-Time Plot Curve with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)

Inspecting a Multi-Time Plot Curve with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)

Figure 5.86: Example Multi Time Plot showing three sub-plots

Example Multi Time Plot showing three sub-plots

You add additional sub-plots to an existing Multi Time Plot window by selecting the property (Property or Curves) that you want and then holding the Ctrl key while you drop it in the window. This will create another plot within the same window. If you do not hold the Ctrl key before dropping the property, instead of being added as a separate sub-plot, the property will be added to the same sub-plot over which you released your mouse over. Tip:While dragging, use the tooltip and hover text to help you determine how and where to drop your data for different effects.

All sub-plots within the same window share the same display settings and can be treated as one image for export (see also Save an Image of the 3D View, Plot, or Histogram).

Like with Time Plots, you can also add an Annotation or a Time Mark to a Multi Time Plot. An Annotation places a mark and caption in a location of your choice on the graph (see also About Creating an Annotation on a Time Plot or Multi Time Plot) while a Time Mark enables you to identify with a vertical line the location of the Current Timestep.

In addition to the standard settings available to all graphs, you can also control how these sub-plots appear in the window by using the Layout tab on the Window Editors panel.

5.3.2.1.3. About Histograms

A Histogram is a type of graph that represents in vertical bars the data set previously tabulated and divided into uniform bins. The base of each bar represents a class and the height of each bar represents the amount or frequency with which the value of the class occurred in the data set:

Figure 5.87: Example Histogram

Example Histogram

5.3.2.1.3.1. Configuring Histograms

Histograms work by aggregating data into separate bins for analysis. One of the benefits of this type of graph is that you can weigh and compare different statistics for different results. For example, you can compare the results of one statistic weighted by another statistic at two different times in the simulation:

Figure 5.88: Example Histogram showing a comparison of weighted statistics

Example Histogram showing a comparison of weighted statistics

Histograms enable you to have even more control over your analysis by enabling you to plot your data in a percentage and/or cumulative manner:

Figure 5.89: Example Histogram showing a cumulative percentage of weighted statistics

Example Histogram showing a cumulative percentage of weighted statistics

These settings are made through a separate Configure Histogram dialog that you access from the top left corner of the Histogram window:

Weight

The method by which you want the selected property(s) weighted for comparison. The weight you choose affects all properties for the selected Histogram. The weight options can include the following:

  • Properties: If you chose to display a Property in your Histogram, then Properties for both geometries and particles will be listed here. (See also About Properties).


    Important:  Though you are able to select any Property you want from the Weight list, only those Properties that are applicable to the Properties you have selected will be shown in the Histogram. For example, if you want to display a Particles Property like Particle Volume, you cannot weigh it by a geometries Property like Area. Doing so will remove the data from your Histogram window until you select an applicable option.


  • Count: This is the default option for both Properties and Curves.

Properties (for both geometries and particles); Count

Number of Bins

Enables you to choose the number of bins or bars the data is aggregated into.

Whole numbers greater than 1

Cumulative Bins

When selected, plots in ascending order the relative frequency of each class (bin) added to all classes (bins) with lower values. A useful method for showing a range of values, this is a mapping that counts the cumulative number of observations in all of the classes (bins) up to the specified bin.

Automatic; User Defined

Min

When Limits is set to Automatic, this displays the minimum value for the selected property as calculated for the current Timestep. (See also About the Time Toolbar). When Limits is set to User Defined, this enables you to set a custom minimum value for the selected property that you want displayed in the Histogram.

No limit

Max

When Limits is set to Automatic, this displays the maximum value for the selected property as calculated for the current Timestep. (See also About the Time Toolbar). When Limits is set to User Defined, this enables you to set a custom maximum value for the selected property that you want displayed in the Histogram.

5.3.2.1.5. About Cross Plots

A Cross Plot is a type of graph that displays in a dot-cloud format correlations between two entity properties (Curves or Properties) that share a common domain (Figure 5.93: Example Cross Plot). Like other Plots, you can also inspect a particular point or zoom-in on a particular area (Figure 5.94: Inspecting a Cross Plot Dot-Cloud with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)).

Figure 5.93: Example Cross Plot

Example Cross Plot

Inspecting a Cross Plot Dot-Cloud with Shift+Click (top left), Ctrl+Click (top right), and Ctrl+Click+Drag (bottom)

One example of how you can use a Cross Plot is to measure the angle of repose of your calibrated material to verify that the simulated particles match real-world results. After creating a sample pile of your particles (Figure 5.95: Simulated particle pile to be measured), you can then create a Cross Plot of the Particle Y-Coordinate position (image) crossed with the Particle X-Coordinate position (domain) (Figure 5.96: Cross Plot of the above particle pile showing the Particle X-Coordinate position crossed with the Particle Y-Coordinate position). Using this Cross Plot, you can then measure the angle of repose.

Figure 5.95: Simulated particle pile to be measured

Simulated particle pile to be measured

Figure 5.96: Cross Plot of the above particle pile showing the Particle X-Coordinate position crossed with the Particle Y-Coordinate position

Cross Plot of the above particle pile showing the Particle X-Coordinate position crossed with the Particle Y-Coordinate position

The two restrictions for creating a Cross Plot are as follows:

  1. The Curves to be crossed must share a common property. For example, given an entity (Particles) that has two Curves [(Pressure X Time) and (Temperature X Time)], there must be a property common to both Curves (Time) in order to generate the desired Cross Plot (Pressure X Temperature).

  2. You may only cross Curves from the same entity. For example, you may not cross a Curve from one type of entity (Particles) with another Curve from a different entity (Feed Conveyor). The Curves must come from the same entity.

Like other graphs you create in Rocky, you can also use the Window Editors panel to change how the graph appears.


Tip:  To see walk-through examples of using a Cross Plot, review the following Tutorials:

5.3.2.2.2.2. About Creating an Annotation on a Time Plot or Multi Time Plot

An Annotation is a special mark that you can add to a Time Plot or a Multi Time Plot that shows a particular data point and caption that you define (as shown below). This is useful in cases where you want to highlight a particular event on the graph to help provide context. For example, you might add an Annotation at the moment when the particle flow reached steady state, when a hopper valve was opened, or when you have reached the maximum mass of particles inside a particular region.

Figure 5.108: Example Annotation added to a Time Plot

Example Annotation added to a Time Plot

You add the initial Annotation and define the text and values from a separate menu button on the graph itself (as shown below) but then can change the display options for it, including settings like font size and position, mark shape, and so on, on the Annotations tab of the Window Editors panel. (See also About Changing the Appearance of a Graph (Plot or Histogram)).

5.3.3.1. About Exporting Data and Images Out of Rocky

There are four main ways you can export data out of Rocky:

  • by saving a snapshot of the selected Rocky window

  • by exporting Plot or Histogram data to a separate CSV file you can review outside of Rocky

  • by copying information, including the snapshot or data values within the window you've selected, to paste into another program

  • by having Rocky collect forces data for the simulation geometries and then exporting that data to a CSV file you can use in a separate FEA program. (See also About Collecting and then Exporting Geometry Forces Data for Later FEM Analysis.)

Notes:

5.3.3.1.1. Saving a Snapshot of a Rocky Window

Taking an snapshot of the 3D View, Motion Preview, Particles Details, or graph (plot or histogram) saves an image of only the display area within the selected window. The other window items surrounding the display area, including buttons and on-screen instructions are not included in the final image (as shown below).

Figure 5.112: A Time Plot window in Rocky (left); the saved snapshot image of the same window (right)

A Time Plot window in Rocky (left); the saved snapshot image of the same window (right)

There are several ways to save an image in Rocky, which produce slightly different outcomes as described below:

  • Save a Snapshot of the Rocky Window, which is accessible through the Export tab on the Window Editors panel and allows you to accomplish tasks like changing the dimensions of the image prior to saving it (Plots and Histograms only) or setting the magnification of the image (3D View, Motion Preview, and Particles Details windows only). Note: For Plots and Histograms, you can access this same information by right-clicking within the window area, pointing to Export and then selecting Image.

  • Save an Image of the Rocky Window, which is accessible through the Windows menu and uses only the current dimensions of the window when saving the image.

See the images and tables below to understand more about how to use the Window Editors panel to save a snapshot.

5.3.3.2. About Collecting and then Exporting Geometry Loads Data for Later FEM Analysis

If you are interested in analyzing how the particle loading will affect your structure, then you can have Rocky record those loads and export them for use in a third-party FEA tool, such as Ansys Mechanical. To do so, ensure you have enabled the collection of Forces for FEM Analysis for Boundary Collisions Statistics before processing your simulation (see also About Collision Statistics for Boundaries). (Note: If you are doing this integration through Workbench, this checkbox will be automatically enabled for you.) After processing, you are then able to export the recorded data into a .csv file. This file can be used in a separate FEA tool—such as Ansys Mechanical—for analysis.

FEM loads can be exported for one or more geometry components in your simulation, and for a single Timestep or a Timestep range that you define. One CSV file is created for each of the selected Timesteps and includes the recorded loads acting on all selected geometries as a result of particle interaction.

5.3.3.2.1. About the Exported CSV File

The CSV files that you export will show the values for the selected load type in each coordinate. The image below illustrates how the data is arranged: the first , the second and the third columns refer to the X, Y and Z coordinates from the geometries you selected, respectively. The fourth , fifth and sixth columns refer to the FEM loads components in directions X, Y and Z respectively, at each coordinate.

Tip:You can also use Ansys Workbench to share the data Rocky collects directly with Ansys Mechanical using a Static Structural Model, or a Transient Structural Model. (See also About Rocky and Ansys Workbench Integration.)

  2. Before processing your simulation, ensure that you have enabled the Forces for FEM Analysis Boundary Collision Statistics option. (See also About Collision Statistics for Boundaries.) Note: If you are setting up your simulation within Workbench, this option will be enabled for you.

  3. Process your simulation. (See also Processing a Simulation.)

  4. When processing is complete, do all of the following:

    1. From the Data panel under Geometries, right-click one of the boundaries for which you want to export forces, point to Export, and then click Geometry Loads.

    2. From the Export Loads dialog, select the geometries for which you want to export forces data, and then under Time Range Filter, define which Timestep or range you want included in the export. (See also About Collecting and then Exporting Geometry Forces Data for Later FEM Analysis.)

    3. Click OK.

    4. From the Select file to export dialog, choose a location and name for the .csv file, and then click Save. One .csv file is saved for each Timestep output in the range that you selected. These .csv files can then be used in your FEA program to analyze geometry forces.
