Evaluate response results

This procedure assumes you have created an event and applied excitations to your model.

Start the evaluation

1. (Optional) Divide the graphics window into two viewports (for example, View→Layout→Upper and Lower). Make sure the Display in option in the Viewport Settings dialog box is set to User Selected Viewport (View→Layout→Layout Setting). Dividing your display allows you to view the model and your plotted response functions simultaneously.

2. One way to specify the range of your evaluation is to graphically select data points from a plotted response function. To use this method, plot a response function and display the graph in one of your viewports, so the model appears in one viewport and the graph in another. In a later step, you will select data points from this graph.

3. In the Simulation Navigator, right-click your Event node and choose Evaluate Contour Results→Response.

4. Under Requested Results, select the types of results you want to evaluate. Note: The result types available depend on the output requests you enabled in the Structural Output Request for the solution (for more information, see Define Response Dynamics result types).

5. If you selected Stress, Strain, or Strain Energy, you must select one or more elements on the model to specify the location of the evaluation. For all other result types, you must select one or more nodes on the model. Note: Use the Selection Method options to easily select all nodes or elements in an edge, body, mesh, and so on.

6. Under Method, select the method of determining the response domain and resolution. The software supports three methods:Start/End Point — Directly specify output range and resolution by typing the values.From XY Graph — Select data points from one or more plotted response functions.Natural Frequency — Select structural natural frequencies (Frequency events only).

Specify a Start/End point

1. Under Method, click Start/End Point. Note: This method is not available for frequency events defined by uneven excitation functions.

2. In the Output Start Point and Output End Point boxes, type the first and last data points in the range to include in the evaluation. Note: The software adjusts output start and end values automatically to follow actual points obtained from the associated excitation functions. For example, if the excitation functions start at time 1.0, the Output Start Point is adjusted to 1.0. If the excitation function end point is at 20 seconds, the Output End Point is adjusted to the closest value based on the Decimation Order. In making this adjustment, the software also considers the event's Duration. For example, if the event duration is 30 seconds, but the excitation functions only extend to 20 seconds, the Output End Point may be adjusted to 30 seconds.

3. If necessary, use Decimation Order to reduce the number of data points. The reduction is based on an order of decimation that preserves the first data point in the function and every nth point thereafter, deleting the rest.

4. Continue to Preview and complete the evaluation.

Select data points from a response function plot

These steps assume you have already plotted a response function in one of your viewports.

1. Under Method, click From XY Graph.

2. Click .

3. Select data points from the XY graph in the viewport where the function is plotted. You can easily select points of maximum or minimum value to define the range of the evaluation.

4. Continue to Preview and complete the evaluation.

Select natural frequencies

Note:

This method is only available for frequency events defined by uneven excitation functions.

1. Under Method, click Natural Frequency.

2. Click .

3. In the Select Natural Frequency dialog box, select one natural frequency from the list. The list shows the available normal mode frequencies (set as Active) in the frequency range of your excitation functions.

4. Continue to Preview and complete the evaluation.

Preview and complete the evaluation

1. (Optional) Under Preview, select the options for the preview evaluation.

2. Click to preview the results. Select the viewport in which to preview the results.

3. On the Evaluate Response Results dialog box, click OK to generate the response results.

4. View the results in the Post Processing Navigator, under the Event node.
