Broadband Source Model Simulation Exercise 7— Analyzing Results
This exercise describes how the results are analyzed during and after the simulation. To hide CAD surfaces (not the fluid domain), switch between 
CAD Bodies and 
Flow Analysis Bodies in the Show group. Clear any variable display by selecting No Selection in the Legend drop-down. Click
XYPlot Panel to view the XY Plot.
