I created a cube and I meshed it in gmsh. After that I imported the mesh in ElmerGUI and I did this steps in this order:

The solver return to me:

Code: Select all

Now I would like to see the potential in 3D space, but when I click on ElmerPost nothing happens, because it replies: 'No ElmerPost input file found'.

Should I generate such a file or am I missing some parameters before the solving process?

Thanks.
