Elmer/Ice performance degradation Haswell to KNL CPUs
Howdy fellow Elmer/Ice Users, I have a short question to experienced HPC Elmer users. The HPC I am running on has recently introduced a new many-core cluster with KNL CPUs. I have compiled Elmer/Ice with its dependencies and it runs smoothly. However, in comparison to the older cluster that uses &qu...

Re: GL dynamics and Stokes in Elmer v8.3
I know a bit late. But rather late than never.
No not at the moment. We have a setup for it that works and gives the same results as NS, but are waiting to get more cores to run it on Will certainly update our versions to latest Elmer version.

A little late, but thanks for the info and the quick fix. All works well again.

Hi Juha,
Thanks for the quick response. Could you give this thread a bump once this has been updated in 'devel'?

Re: Changes to parstokes Solver?
Hi Peter,
So here is a test case Thomas presented at the last Elmer/Ice course that used to work without problems, but now crashes with a segfault.

Changes to parstokes Solver?
Hi y'all I updated to a newer code version of Elmer a few days ago and wanted to start optimising my Par-Stokes set-up. With the old version the code runs smoothly, but with the newer version it only works if I comment out the line Element = "p:1 b:4" in all three solvers. However doing th...

Re: ParStokes for sheet-shelf and basal sliding
Hi all, just for people who'll come across the same problem in the future. It is indeed necessary to change a line in USF_Contact.f90. Instead of VarSurfResidual => VariableGet (Model % Mesh % Variables, 'Flow Solution Loads', UnFoundFatal=UnFoundFatal) It needs to be changed to VarSurfResidual => V...

Re: ParStokes for sheet-shelf and basal sliding
OK I did some digging. So the segfault came from the USF_sliding user function, where it wantst the Flow Solver Name. If none is set in the solver section, it is set to Flow Solution. By setting Flow Solver Name = String "FlowVar" in the ParStokes solver section this segfault went away. Th...

ParStokes for sheet-shelf and basal sliding
Hi all, I’m trying to set up the ParStokes solver for a 3D sheet-shelf simulation. I’ve got it running with no basal sliding under the sheet, but when I turn on basal sliding it gives me a segmentation fault. The culprit appears to be the UserFunction "SlideCoef_Contact". When I comment th...
