Hi!<br><br>I'm currently using Gmsh to get surface plots of real valued functions on a mesh on the unit square (z-value of surface is proportional to function value). 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?<br>
<br>I'm using Gmsh 2.6.1 on Redhat Enterprise Linux 6.3.<br><br>Best regards<br>Torquil Sørensen<br><br>
