Electrostatic potential of a cube of steel
Posted: 06 Feb 2019, 16:32
I'm trying to solve a simple problem to make practice with this software.
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:
It seems that all is ok.
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.
