How to compare 2 meshes?
 

I got 2 meshes, one from Ansys ICEM and exported as Star-CD format (.vrt, .cel, and .inp). Then the exported mesh has been modified in some other software. What I'd like to do is to compare the two meshes against with each other for the displacement. Is there any software available that is capable of doing that? A heatmap like comparison would be ideal. Thanks.
