Creating Data Tables

A data table is a grid with rows and columns that displays, in numeric form, selected quantities against a swept variable or other quantities.

1. From the Maxwell 3D or Maxwell 2D menu, select Results > Create <type> Report, or right-click on the Results entry in the Project Manager tree and click Create <type> Report.
2. In the display type menu, click Data Table.

The Report dialog box appears.

3. In the Context section make selections from the following field or fields, depending on the design and solution type.
• Solution field with a drop down selection list. This lists the available setups and sweeps. As a minimum, the LastAdaptive solution and AdaptivePass solution is available to choose.

  The AdaptivePass solution context can be selected to allow any value or parameter to be plotted versus the adaptive pass. This function is usually used to evaluate the convergence of the solution.

• For Transient projects only: Domain field with a drop-down selection list containing options for plotting vs time (Sweep Domain) or plotting vs frequency (Spectral Domain).
• For Transient projects only: Domain field with a drop-down selection list containing options for Average and RMS and Transient D-Q for electric machines. Click Machine Options to setup the machine specific parameters.
• For Eddy Current projects only: Domain field with a drop-down selection list containing options for plotting vs frequency (Sweep Domain) or plotting vs time (Time Domain).

  Matrix field with a drop-down selection list containing options for plotting matrix and reduce matrix parameters.

  Note: In Maxwell Eddy Current designs, the user can create matrix parameters, which will cause the solver to produce an impedance matrix for the selected excitations. In addition, the user can group (wire) two or more excitations to one excitation in either a series or parallel connection referred to as a reduce matrix. The Matrix field appears only if a matrix entry is selected in the Parameter field. (Refer to Assigning a Matrix for information on creating a matrix and Assigning a Reduce Matrix for information on creating reduced matrix parameters for Eddy Current designs.)

  

• Parameter field with a drop down selection list. Whether this field appears, and the parameters listed depend on the Solution type and the <type> selected.
• For Fields and Noise Vibration reports: Geometry field with a drop down selection list. This applies the quantity to a specific geometry.
4. Under the Trace tab, Y component section, select the quantity you are interested in and its associated function:
1. On the Category drop down list, click the type of information to plot.
2. On the Quantity list, click the values to plot. Use Ctrl-click to make multiple selections.
3. In the Function list, click the mathematical function to apply to the quantity for the plot.
4. The Value field displays the currently specified Quantity and Function. You can edit this field directly.
   Note: Color indicates a valid expression.
5. The Range Function button opens the Set Range Function dialog box. This applies currently specified Quantity and Function.
5. On the Trace tab, X (Primary Sweep) line, select the sweep variable from the drop down list. By default All of the chosen sweep’s values are used. You can also select the browse [...] button to display a dialog box that lets you select particular sweep values, specify a range of sweep values (for Time sweeps), or Use all values (the default setting).
6. On the Families tab, confirm or modify the sweep variables that will be plotted.
7. Click New Report.

This creates a new report in Project tree, displays the report with the defined trace, and enables the Add Trace button on the Report dialog box. The default name is based on the Report Category you selected, for example, Force Plot n or Output Variables Plot n. You can edit the plot names in the project tree and the plot header text in the report synchronizes.

The Y quantity will be listed at each variable value or additional quantity value you specified. The data table is listed under Results in the project tree. The plot is listed under Results in the project tree and the traces are listed under the plot. When you select the traces or plots, their properties are displayed in the Properties window. These properties can be edited directly to modify the plot.

8. Optionally, add another trace to the plot by following the procedure above, using Add Trace rather than New Report.

You can also modify the display type of an existing plot from the Properties dialog for that plot. Select the Report icon in the Project tree to display the Properties dialog box. Selecting the Display Type field displays a menu with selections available for that plot.

Once you make a selection, the plot display updates for the current selection.

If you choose to print a data table:

• Selecting print "All" prints the whole table for current data page (if there is more than one data page).
• Selecting print "Pages" prints user-specified pages.
• If the table is bigger than the screen view (that is, it has a scroll bar), printing first scrolls right, prints until no more scrolling occurs, and then scrolls down.
• The Page number appears at the bottom of the page, aligned at center.
• The table layout of each page follows the screen, but without the scroll bar being printed, and no data page bar as on screen.
