To show an example, how to use the "Chain Multipe Models".

Step 1:

The first step is to load each run through the File menu (File → Open → Binary Plot). The number of models loaded will be shown in the model selection list.

Figure 6.144: Models Loaded

Figure 6.145: Control Shown

Step 2:

By selecting a model from the list and pressing the Apply button, a sequence list can be built in the list below.

The starting state, ending state, and increment for each model are determined by LS-PrePost automatically ( or they can be modified by the user for each model ).

Figure 6.146: Apply And Setting

Figure 6.147: Control Shown

Step 3:

Finally, after composing a sequence, the Chain button can be pressed. This will chain the selected models together. The animation interface can be used for various animation adjustments at that point.

To unchain the sequence, the Unchain button can be pressed to proceed with normal single model animation and processing.

Step 2:

Select "Element" radio button. Then select a component in history component list. Take the component of "Effective Plastic Strain" for example, this item is selected.

Load a d3plot file.

Open Setting->Reflections interface.

Check Whole and XY .

SPH nodes sample:

Load a keyword file.

Create SPH mode with SPH Generation.

Select sphnd with Assembly and Select Part.

To give some samples to show how to use reference state, overlay state, fringe difference state and multiple state functions.

 

6.6.8.1. Reference state:

Step 1:

To load a d3plot model, click the select radio button, and select one state in the state list. To select the second state like this, the neighbor states shown for compareing with each other clearly.

Figure 6.157: The 1st State

Figure 6.158: The 2nd State

Figure 6.159: The 3rd State

Step 2:

Check the Ref State to change displacement reference state to on, and enter reference state index number to 2.

The other states displacement will be base on the second state, and the second state will be shown to initial state for displacement. Like this,

Figure 6.160: The 1st State

Figure 6.161: The 2nd State

Figure 6.162: The 3rd State

 

6.6.8.2. Overlay State:

Step 1:

Check the overlay state to turn on overlay mode, and enter an overlay state index number to 1. Select overlay color to green and drawing type to mesh.

Step 2:

Select another state in state list. It will be shown like this, the shade sate is the overly state, which is the first state in this model. The green mesh state is another state in the model.

Figure 6.163: Overlay

 

6.6.8.3. Fringe Difference State:

Step 1:

Load a d3plot model, go to state dialog, select one state in the state list. Take the third state for an example.

Step 2:

Go to fringe dialog to show some fringe data. Click the stress button and select the "x-stress" in the list. The x-stress fringe data will be shown in the model, like this,

Figure 6.164: X-Stress Fringe 3th State

Figure 6.165: Fringe Levels

Step 3:

Go to state dialog, turn on fringe difference mode, and enter the state index number. The fringe data which is the difference between setting fringe defferece state and the selected state in the state list will be shown.

e.g, to set the fringe difference state to 3, select the 3th state in state list. There will be noting difference between them, like this,

Figure 6.166: Differece X-Stree Fringe Between 3rd and 4th State

Use the New XYPlot Frame to plot element component history values. The operations of plotting other components value are similar to this sample. After mutiple xy datas have been plotted in the main window, they will be shown in multiple pages, and there are several frames in one page. Operate the New XYPlot Frameand browse mutiple xy data result.

"Interpolate" could be checked to linearly interpolate curves before plotting, and set number of divisons for interpolation, default it's 1000.

User could skip this step, if it's not necessary.
