I pushed a version to elmerice-branch that derives valid Equation from the parent element. Issues might occur on body-body boundaries, but the EISMINT case should now run without the extra body on the boundary.

Hi, I think the core issue here is that you want to inquire something from an Equation section out of an USF that not directly relates to one (as else it'll be a Solver). In other words: there is no direct relation between USF's and Equation section. In the working example the only reason why it did...

Hello, the issue lies within line 184 in USF_GetFrictionHeating.F90 Equation => GetEquation() Which picks the current element and tries to assign an Equation from it. In case the boundary element the USF is executed on has no assigned body (plus an Equation to be applied to it), this will be an unas...

Martim, I know this answer comes vastly delayed, but could you try to use the new vectorized Navier Stokes solver with the block preconditioner to avoid running into memory issues? You can find examples on how to deploy it under the latest course pages http://elmerfem.org/elmerice/wiki/doku.php?id=c...

Hello there is active work going on to get a remedy for this instability. But until then, I am afraid, the only way to avoid instability is to reduce the time-step size. In particular, the no-slip condition on the bedrock does not help. What is your minimum flow-depth (i.e., your RefZs - 0.1 ?). Inc...

Kai,
could you share "test-stderr_6.log" and "test-stdout_6.log" by their contents? This might give a clue on what went wrong.

I think every initialization run of any real-world geometry with marine ice sheets involved (e.g., Antartica from BedMap2 or perhaps even BedMachine) faces that issue, as shelf-geometries usually are inconsistent with floatation.

Hello,
yes, the launchpad version should include Elmer/Ice

given in terminal will show you options

yes, any successful Elmer installation should contain ElmerGrid - if not, something went wrong
