How to exclude a region from a Finite Element Analysis? 1

[LeonardoArantes]

Hi, I do use CATIA V5 Advanced Meshing workbench to mesh the part however I need to remove a region because it evaluates not accurate results due to rigid coupling...
Is there any way to ignore these values when plotting the results?
I've attached a screenshot indicating the area I need to "ignore", it is between the inner and the outer circle.

Usually, color scale adjustment is sufficient to hide too high stresses and make the lower ones more visible. Most postprocessors allow you to do that by just specifying a custom upper limit.
