Is it possible to tell Gmsh to show the difference between two such functions, so that I can easily see if they are equal by visually inspecting if the difference vanishes?

Hi Prof. Christophe Geuzaine!
I managed to do it with the MathEval plugin as you recommended. My two
plots were view 0 and view 1. So I selected View=0, OtherView=1, and
Expression0=v0-w0. It worked perfectly!
