Display overlay FRFs at specified stretch parameter

To plot the overlay FRFs at the selected stretch factor beta, you must first create a FRAC plot.

Create FRAC plot

1. In the Simulation Navigator, click the FRF Pairing [#] node.

2. In the Correlation Details View subpanel, right-click one or more FRF pairs and select Plot FRAC→FRAC.

3. In the Stretch Factor Options group, in the Increment box, enter 0.01.

4. Click OK.

5. In the Viewport dialog box, do one of the following to select where you want to display the plot:To plot the FRAC plot in the main graphics window, click Select Viewport by Cursor , and then click in the graphics window.To plot the FRAC plot in a separate graphics window, click Create New Window .

6. Click OK.

Create FRF plot at specified stretch factor

1. Right-click in the FRAC XY plot and choose Probing Mode→SingleX.

2. Use the help line to select the stretch factor beta at which you want to compare the work and reference FRFs.In this example, the overlay FRFs are plotted at stretch factor β equal to 1.01.

3. Right-click the help line and choose Overlay FRFs to overlay the work and reference FRFs for all the FRF pairs in the graph.

4. In the Viewport dialog box, select where you want to display the plot.

5. To plot FRFs for one or more selected pairs, in the FRAC color bar graph, select as many as Probing Text associated to the FRAC value that you want, right-click one of the selected Probing Text and choose Overlay FRFs.

6. In the Viewport dialog box, select where you want to display the plot.
