GL dynamics and Stokes in Elmer v8.3

Dear ElmerIce users, Following important changes on how Dirichlet Conditions are handle in Elmer v8.3, we found that the conditional dirichlet condition for the normal velocity in the grounded part of the ice sheet was not properly released during grounding line retreat. This has now be fixed in the...

Re: Elmer/Ice tests

Hello Rupert, thanks for the report and sorry for the late reply. At Grenoble we are running all the Elmer/Ice tests, after each code revision. I try to keep an eye on the results as much as I can. I have updated most of the tests with failure. On the 52 elmerice tests (ctest -L elmerice); There is ...

Re: Pb with conditional Dirichlet

Hi Peter; Yes a call to DefaultInitialize() will also solve our problem. Currently we have this problem with the Navier-Stokes solver, I see that it is calling InitializeToZero(). Replacing the InitializeToZero() line by CALL DefaultInitialize() will sove our problem. I see that there is few other s...

Pb with conditional Dirichlet

Hello; It seems that Solver % Matrix % ConstrainedDOF is never reinitailised to FALSE so that when a node get a Dirichlet condition, it will always apply a Dirichlet condition. This could be a problem when using a "Condition" for the dirichlet condition and when the condition change from TRUE to FAL...

Re: Passive condition

Hello Peter; Here is two tests for the passive condition keyword. I have been a bit confused as I get the expected behaviour for solvers with DOFs > 1 (e.g. Stokes); this is because the values for each component are set in a second round where it does not visit the section that reset the values to t...

Passive condition

Hello, Dirichlet conditions for passive elements (set with the keywords VarName Condition Passive = Logical in Body Forces) are not taken into account anymore due to changes in how Dirichlet conditions are set. Lines 4700 to 4728 of SolverUtils.F90 take care of the matrix entries for the passive ele...

Re: YAMS installation problem

ok; thanks for the report.
I will update the wiki page and try to sort out the errors for versions from 5.3.0

Hope you will find the examples in the Test directory usefull. If you need more details on the mesh adaptation; dont hesitate to ask.

best regards

Re: YAMS installation problem

It seems that there is some incompatibilities with the newest revisions of mmg. - In your mmg clone directory could you revert to an old revision: git checkout 6acfa9e7b20e41134d56af10eba1bb8fd1283f8f - compile and install mmg from this revison - and try again to install Elmer. Please let me know if...

Re: YAMS installation problem

Hello, Yams was used in a pre-processing stesp to adapt the mesh using an error estimator. I have recently implemented very similar codes directly in Elmer. Documentation can be found here: http://elmerice.elmerfem.org/wiki/doku.php?id=mesh:meshadaptation It requires to install an external library M...
