Hi Martin, I had a quick look at your case. I think what's actually happening is that MUMPS is throwing an allocation error and giving up, resulting in no velocity computation. Basically, your mesh is too fine for whatever system you are running on (and indeed too large for my own desktop computer)....

Hi all, I had previously done some investigations with a basal channel mesh. I have been rather busy recently and haven't had time to continue investigations into this, but Brandon provided me with the mesh they use in their investigations (subaerial calving at the right margin). I can provide this ...

Small piece of info regarding emacs, the default indentation level is 3, and this can be changed with: (setq f90-do-indent 2) (setq f90-if-indent 2) (setq f90-structure-indent 2) in the .emacs config file. Also, the following will take care of syntax highlighting and should cause keywords to appear ...

Hey, For the temperature problem, did you set the following in the temperature solver section? Loop While Unconstrained Nodes = Logical True For the values of the parameters you mention, reasonable values are listed on this page: http://elmerice.elmerfem.org/wiki/doku.php?id=problems:rheology&s[]=glen

Hi Saisai, It'd be more useful to see the logs of your installation to see why the elmer/ice installation failed. When you do bash elmer_install.sh you could pipe the errors to a log file like this: bash elmer_install.sh 2>&1 | tee LOG and then either upload the whole LOG file somewhere, or have a l...

Hi Saisai,

What errors did you encounter when installing elmer/ice?

Hey Peter, Thanks for getting back to me. I tried modifying the temperature solver to set MeshVelocity = 0.0 internally when running in steady state but this didn't make a difference. I've tracked the problem down to the recomputation (I think) of the stabilization parameters within DisplaceMesh. I ...

Hi all, I'm encountering some strange convergence issues in the temperature solver in a coupled NS/Heat equation + mesh update spinup run. Although my simulation is transient, I'm attempting to solve the steady state temperature equation by specifying: Steady State Condition = Real 1.0 in the Temper...

Hi Sharon, It's possible to do this as an accumulation term in the freesurface equation, but I think that it's more accurate to directly account for the addition of mass in the stokes equations. I wrote some code to do this in a flowline case by adding a "Pressure Load" following Peter's advice in t...

Hey Peter,

In all the cases where this error occurs, it seems like the point is not within the element, so I suppose within the context of interpolation, it's probably not an important error.

Cheers,

Joe
