Hi again,
Does this Mesh2Mesh works in parallel?
Problem is that I don't have the same number of processors in my coarse mesh runs than in my fine mesh runs.
Is this going to work or am I asking for too much?
Thanks
Denis

Re: Coarse to fine mesh interpolation
Hi everyone,
Thanks for all your response.
I'll try your suggestions and get back to you.
I do want to interpolate to restart a new simulation on a finer mesh.
Thanks
Denis

Coarse to fine mesh interpolation
Hi everyone,
I'd like to interpolate results (velocity/pressure/temperature) from a coarse mesh onto a fine mesh.
Are there tools in Elmer/ElmerIce to do such operation?
Thanks
Denis Cohen

Re: Problem with solving temperature after inverse method
Hi Martina, Unfortunately this is a paleo ice stream so no data on velocity so no way to invert for a sliding coefficient. It seems that a finer mesh improves the velocity field at the bed (no more sliding velocity > surface velocities). Still some temperature that our too cold for some unknown reas...

Re: Problem with solving temperature after inverse method
Hi Martina, I am setting Mesh Velocities to zero and that works fine. It's a bit confusing when doing a restart but I got it to work. You may be right about a Slip Coefficient that is not constant under the glacier. How did you apply a non-constant slip coefficient? What did you use to make it varia...

Re: Problem with solving temperature after inverse method
Hi Martina, Curiously my problems are more when I try steady state simulations than when I do transients. Transients have (almost) always converged. In my problem I start with a given glacier geometry and temperature and I first relax the free surface (not solving for Temp) for 50-100 years (or more...

Re: Problem with solving temperature after inverse method
Hi Everyone, I am writing to this post instead of opening a new one since I think this is a related problem. I am solving a paleo ice-flow problem, trying to reconstruct part of an ice field at the LGM so I have no temperature or ice velocity data, only a bed and ice surface DEM. First, I start with...

Re: error DetectExtrudeStructure
Hi Peter,
I have no lateral deformation, only z, so should be keeping a nice extruded structure.
So I guess it's ok to use the internal extruded mesh and the Mesh Update together.
Will look to see what gives.
Thanks
Denis

Re: error DetectExtrudeStructure
Hi Peter, No this happens in the first NS solver call. Before that it went through the StructureMeshMapper with no apparent problem: StructuredMeshMapper: --------------------------------------- StructuredMeshMapper: Performing mapping on a structured mesh StructuredMeshMapper: ---------------------...

Re: error DetectExtrudeStructure
Hi Peter, Indeed a small stupid mistake. That + playing with the dot product solved this problem. However, I am puzzled by another, which again may have a simple answer: In the NS solver I get this error: FlowSolve: ------------------------------------- FlowSolve: NAVIER-STOKES ITERATION 1 FlowSolve...
