Re: elmerf90-nosh and Elmer/Ice tests

Hi all, I am new to cmake and want to run the elmerice tests. A naïve install using cmake doesn’t seem to activate the ElmerIce tests for me. The elmerice/Tests directory is present in the build directory but without the subdirectories for individual tests. The fem/tests directory, however, does see...

Re: Non-smooth weertman basal velocity

Hi Christian, the "Normal-Tangential Velocity" setting is local to the boundary condition in which you apply it. You don't need to "undo" this. Are you using a spatially uniform basal drag coefficient? If so then the non-smooth basal velocity might arise from a non-smoth bedrock. I am guessing your ...

Elmer/Ice test cases

Hi all, I am currently running the test cases, which I haven't done before, and I notice some failures, albeit by fairly small margins. Do these look worrying to you? Cheers, Rupert ============================================================= Test ElmerIce Solvers Option []: All tests without email...

Re: ElmerSolver test case how-to

So, much better than before, nearly all pass. Should I be concerned about the few that fail? Or does this look acceptable? ... test 151 : levelset3 [FAILED] Computed NRM=.373585E-001 Target NRM=.503468E-001, look at [levelset3/test.log] for details ... test 171 : mgdyn_lamstack_lowfreq_harmonic [FAI...

Re: ElmerSolver test case how-to

Hang on, I had a link that pointed to an older version of ElmerSolver. I am re-running now with svn version 7029. I get fewer fails, but still not all tests pass. I'll post again when it finishes...

Cheers,
Rupert

Re: ElmerSolver test case how-to

Hi Peter and co, should we expect all tests to complete successfully? I am running the tests now because I plan some minor commits soon and I want to check I haven't broken anything. When I run the tests I get a number of individual fails but at the end it says the test has passed successfully... is...

Re: non-reproducible machine-specific convergence failure

Thanks Thomas. I am guessing either something to do with MUMPS or MPI libraries, but I'll check after installing the same Elmer version first as that is the easiest thing to do. I guess I'll try installing MUMPS next rather than using the default MUMPS installation we have here. Which libraries does...

non-reproducible machine-specific convergence failure

Hi all, not sure whether to put this in the Elmer/Ice section or in the main Elmer section as it is probably not ice-specific, though I am not yet certain! I am running flowline marine ice sheet simulations. I am running on Taito (CSC machine in Finland) and on Raijin (NCI machine in Australia). Som...

Re: Trouble with lateral friction

I've now tried this with the Weertman and also the Coulomb/Cavity sliding laws and get the same problem: non-convergence in the nonlinear Stokes iterations when a significant lateral drag is applied.

I've varied the thickness of the initial slab, still the same problem.
