Power Inverter without Heat Transfer: Exercise 7—Analyzing Results
This exercise describes how you analyze the results 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.
