For the second question:
I don't see a standard solution for that, since the location of the maximum CPRESS is probably changing during the simulation. But a Python script could do this. And I think it should not be too hard to create it. It is basically a script like the example in the Scripting Manual, but now with an additional loop over the result frames. And when the data are queried, then it can be added as table in A/CAE and displayed as curve.
What is possible with existing methods:
- Visualize a result for one location in an xy-plot
- Search the maximum result over all frames and visualize them in one contour plot
