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,

Thomas

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...

Re: trouble going from diagnostic to prognostic

Initial Condition 2 Zs = Variable Coordinate 2 Real cubic include "icescarp70degground.dat" End RefZs = Equals Coordinate 2 End should do it. So no "Equals" for the Zs-initialization. And then, of course, you have to take care that the solver that updates the mesh (StructuredMes...

Re: trouble going from diagnostic to prognostic

The main issue is conected to the fact that your "Top Surface" keyword points to the initial data all the time, but rather should point to the result of your free-surface evolution equation. So, the good strategy would be to let the initial shape define the initial condition for the free-s...

Re: Help to simulate Sheet/Shelf problems

Hello,
seems you want to solve the Grounding Line Problem, which for 2D is explained (including link to example) under http://elmerice.elmerfem.org/wiki/doku. ... undingline

Good luck!

Best Regards,

Thomas

Re: Setting basal pressure til fraction of overburden

Hi, perhaps the name "External Pressure" is misleading. It is basically the normal component of the Cauchy stress vector, which is the Cauchy stress tensor dot product with surface normal. It follows from the weak formulation of the Stokes equation. It is a Neumann condition to the system....

Re: Setting basal pressure til fraction of overburden

Hi Christian, I guess you are using this 0.6*overburden as the effective normal pressure in some sliding law, right? Did you check that your values are dimensional consistent with the rest of your material parameters? Simply, if you do your computations in MPa-a-m system (which usually is the case i...

Re: Test failed for test case 3 (Contact) in Elmer/Ice

So your case went through - something then went wrong outside the run. Reading your error message from before, my suspicion is, that perhaps your permissions for the test subdirectory are such that you are not allowed to write anything into it. If you do a chmod -R u+rwX contact does it help? Best R...

Re: Test failed for test case 3 (Contact) in Elmer/Ice

Hi, unfortunately, I am not able to reproduce your error. Could you try to go into the subdirectory of this test and run it manually and send the output. To that end, you have to declare the following variables (provided you are running bash) export ELMER_GRID="ElmerGrid" export FORT="...
