Re: ctest failed due to segmentation fault errors

One more hint I got yesterday from a colleague for OSX: one frequent cause of troubles could be the Blas library provided by Apple. If I understood correctly, there might be a way to replace it by one from homebrew. Dunno if this helps

Re: ctest failed due to segmentation fault errors

Hi Michelle, we are working on a documented plan how to install on OSX. For your CentOS installation: you definitely want to have MUMPS and easily can forget about Hypre if you are doing glaciological problems. On RHEL I found a RPM package for MUMPS in the EPEL repository and this looks very promis...

Re: ctest failed due to segmentation fault errors

Michelle, the ctest is meant for testing _before_ installation, hence falls back on the binaries inside your build-tree. Hence, all paths there are more or less hard-coded. If you change something after compiling (renaming, copying), this might cause problems. Else, I am lacking any explanation for ...

Re: ctest failed due to segmentation fault errors

Hello, checking your logs, it seems to me that the ctests want to access directories that a) either do not exist b) are not set for permission CMake Error at /Users/johnchristian/Elmer/elmerice/elmerice/Tests/test_macros.cmake:70 (FILE): file failed to open for reading (No such file or directory): /...

Re: ParStokes and ice shelves

Dear Martin, if your "normal" Stokes solver produced a solution, then - in principle - the ParStokes should do so, too. Could you please indicate which part of ParStokes refuses to converge: the outer (GCR) system or one of the block-preconditioning sub-problems? Do you have grounding-line...

Re: ctest failed due to segmentation fault errors

Hi Michelle, this is a little bit tricky to analyze remotely, not only (but mainly) because of OSX. I think a good start would be, if you could send the log of the seg-faulted test (should be under Testing/Temporary in your build-directory) and perhaps give us hints how you configured your environme...

Re: Elmer-2Dglaciertoymodel

Dear Kevin, the "side" boundaries in the test example for the Reykjavik course simply set the horizontal velocity component (what ever direction this is in your model, in ours it is X or direction #1) to zero while leaving the vertical (in our model Y or #2) without a Dirichlet condition, ...

Re: ParStokes example .sif?

Checking the code, it seems that the dimension of the problem is being taken care of - i.e., I found no reason why it shouldn't work in 2D. Question is - do you really need it in a 2D problem or are you equally happy with the standard Navier-Stokes Solver and a direct solver?

Regards,

Thomas

Re: elmerf90-nosh and Elmer/Ice tests

Hi Rupert,
your issue might be connected to the fact that the default branch is "devel" and not "elmerice".
A

Code: Select all

git checkout elmerice
might be at place.

Regards,

Re: trouble going from diagnostic to prognostic

Hello, I didn't realize your MeshUpdate in the first instance - sorry. Then you can do it such that you just initialize, imposing the data directly to Top Surface and then couple the FS to the MeshUpdate variable, sacrificing the advantage of having a vertically structured mesh. Or, you do as I sugg...
