Re: Reading gmsh mesh with elmer (ElmerGrid/Elmer GUI)

ElmerGUI File > Open > <fileName>.unv converts the unv file to an Elmer Mesh and opens it. ElmerGrid.exe 8 2 <fileName>.unv -autoclean converts the unv file to an Elmer mesh and stores it in a folder named filename To open the ElmerGrid mesh you would use the load mesh command in ElmerGUI. In my exp...

Re: Structures with hinges

It has been done before, can't find the example right away, but will keep looking. Done with chapter 9 of the solver manual. Mortar conditions.

Re: Debian removal of Qt4 in Bullseye and beyond

It would be reasonable to demand that Debian and Ubuntu continue to support Qt4, but they are not. It will take a while and significant effort for other packages to upgrade code from Qt4. It will not be "fixed" soon.

Re: Serious problems compiling ElmerGUI on Ubuntu 20.04

I do not know of any case of ElmerGUI being compiled successfully in Ubuntu 20. Ubuntu 20 doesn't work with Qt4. I even tried to update the ElmerGUI Qt4 code, but Qt quit supporting many of the functions used in ElmerGUI. The only options I could find on Ubuntu 20 was to use a VM. However Ubuntu 20 ...

Re: Is Unstable convergence history normal

Unstable convergence is normal for unstable problems. Numerical solutions can start stable and become unstable as conditions change. Computer solutions of numerical solutions can become unstable due to many issues, mesh size, time step size, etc. There are many examples in fluid flow cases where the...

Re: Unable to start parallel solver

If you were doing it from the command line and the elmer exec was in C:/elmer/bin then it would be but I thought windows was \ and unix was /, so maybe you need to change the slashes C:\Program Files\MPICH2\bin\mpiexec.exe -n 4 C:\elmer\bin\ElmerSolver_mpi.exe If you have the slashes right then the ...
