Re: Problems with basal sliding when applying Porous Solver

Dear Elmer users,

the problem with convergence has been finally solved by applying the GCR method with the restart parameter equal to 300 and the ILU0 preconditioner in the Porous Solver section. Thanks fgillet for the useful recommendations!

Re: Problems with basal sliding when applying Porous Solver

Hello, fgillet!

Thank you very much for your reply and recommendations. I will try to do everything that you suggested. Unfortunately, I have not managed to attach any files, although not all of them were too large. I will try to fix it somehow.

Dear Elmer users, I am trying to introduce basal sliding into a thermo-mechanically coupled model for a polythermal mountain glacier. I use snow/firn rheology (Porous Solver). If I apply no-slip conditions at the bedrock, the case works. But when I set the basal boundary condition as described in El...

Re: Problems with executing Elmer/Ice examples

Dear Oliver, thank you once more for continuing helping me. Sorry for disturbing you again. I have moved in the TestGlacier directory as you suggested and it helped. The system is now able to find file Stokes_diagnostic.sif. But unfortunately a new error message appeared and the file stokes_ela400_d...

Re: Problems with executing Elmer/Ice examples

Dear Oliver, thank you very much for your reply and advice. I have tried what you suggested. Nevertheless, I didn't succeed in solving my problem. In fact, directory TestGlacier already includes file testglacier.msh and directory testglacier , and when I perform gmsh -1 -2 testglacier.geo it creates...
