GL dynamics and Stokes in Elmer v8.3
Posted: 10 Apr 2018, 11:04
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 latest commits under the dev and elmerice branches.
This was affecting transient simulations with grounding line dynamics with Stokes (and eventually ParStokes; is anyone using ParStokes to model grounding line dynamics?).
If you are running such simulations please update your code to the latest revision.
