I recently installed Elmer on my mac machine. I am trying to rerun a case that I successfully ran on an elmer installed on a Windows before. I am using the same Mesh.inp file and for some reason, ElmerGui doesn't show the mesh after loading it. I have tried it several times, and only once when I clicked on the remesh button, the mesh was showed up.
The following text is shown on the terminal after loading the mesh over the gui. Does anyone have any idea?

1. Make sure that at least View -> Surface Mesh, maybe also View -> Volume Mesh is checked in ElmerGUI
2. Try to open the Elmer Mesh files from your old Windoze project on the Mac (using File -> Load Mesh).
3. Convert the inp file with ElmerGrid on the command line and see if the resulting Elmer Mesh files can be viewed in ElmerGUI.
If 2. and 3. work, it's a problem of mesh import in ElmerGUI. In that case, 3. could be a workaround.

Thank you very much Matthias.
For some reason, it sometimes works and sometimes doesn't. But it's not a problem any more.
Now, I've got a different problem. I'm trying to run some electrical flow simulations. For now, I'm trying to reproduce a case that I've already successfully done in Windows. But for some reason, the ElmerSolver doesn't work. It doesn't crash or anything. It just ends after it starts solving for the mesh and gives me nothing but a Zero potential field. The version I tried on Windows was 7, but on my Mac I have V. 8.1. Do you think it might be because of that? Do you know how I can download an old version on mac using github?
I don't know anything about Elmer on Mac.
I would
1. do a diff between the sif files on Windows and Mac
2. look carefully at the solver output for errors or warnings (does it find the mesh? all libraries, keywords, ...)
3. make sure that really that case worked in Windoze, with everything exactly as it is on your Mac
4. if that doesn't give an indication, revert to Elmer 7, but I don't know how to do that for Mac...
