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.
Viewing the Pressure Contours on a Boundary
Pressure: [Pa] : Flow
101325

3. Click XYPlot. A new entity xyplot2 is added in the Flow Analysis Tree under Results > Derived Surfaces > XY Plots.
4. Select xyplot2.
5. In the Properties panel, View tab, set Variable as Pressure.
6. Click Stop and Run, if required.
