In HypermeshCFD post-processing, how can I extract data for a specific region?

Question

I want the average velocity within the red selection box, not the average for the entire cross-section. How should I proceed with the selection?

Using Finite Slice Planes may be the best option.  You end up with a slice plane covering the desired area - then use the Integration or Engineering Quantities tool on that reduced-size slice plane.
