Re: Transfer basal drag from one mesh to another mesh
for massively parrallel you can use the keyword: Bounding Box dx = Real XX Only data points that are within Max/Min mesh corrdinates (of the current partition) + the real Value XX will be transfered to the interpolation library ((Default) no bounding box); This could become problematic with very lar...

Re: Transfer basal drag from one mesh to another mesh
Yes best with "savedata" "saveline" to save values on a boundary;
But it is always possible to save csv files with paraview if you only have vtus results.
then "awk" to produce "x,y,value"
fab

Re: Transfer basal drag from one mesh to another mesh
Hey, to do this I often save my results in an ascii file (x,y,value) and use the Scattered2DDataInterpolator ( http://elmerice.elmerfem.org/wiki/doku.php?id=solvers:scattered) to interpolate in the new mesh. This solver use external librairies that implement Natural neighbours and cubic spline inter...

Re: unique global node identifiers?
Hi, look at the ParallelInfo_t type; the array GlobalDOFs (e.g. Mesh % ParallelInfo % GlobalDOFs) will give you the global node numbering. The other structures will give you informations about neighbours etc... Not sure if it is documented somewhere; better to directly look in source codes to see ho...

Re: AIFlow fabric directionality
Hello, I have commited a fix for the computation of the euler angles for the fabric orientation in 3D. But I think, as I understand you cylinder set-up, that your results are correct, i.e. vertical one maximum fabrics are more favorable than horizontal 1 max fabrics. For perfectly aligned fabrics (i...

Re: Bedrock Sliding Boundary Condition
Hi, It's the iterative method for the linear system of the free surface (Solver 6) which is not converging. Increasing the verbosity level (Max Output Level = I in the Simulation section; max I=42) can sometimes help to see where the problem comes from. Have you checked your velocity field (you can ...

Re: Bedrock Sliding Boundary Condition
Hi,
Have you tried to use only Picard iterations (I see in your Navier-Stokes solver that you switch to Newton after 5 iterations)?
This is the first thing to try when the non linear iterations diverge.
cheers

Hello; which version of MUMPS are you using? looking from the MUMPS versions changelog.: from 4.8.4 to 4.9: 18. Message "problem with NIV2_FLOPS message" should no more occur from 4.10.0 to 5.0.0: 24. Message "problem with NIV2_FLOPS message" should no more occur (there was still...

Re: Inverse Methods with SSA
Hi David, you're right the Adjoint and Robin methods in the Elmer/Ice distribution are for Stokes only. I have developped the adjoint tools to invert viscosity or/and basal slipperiness with the SSA solver. You can find an application in this paper in discussion for The Cryosphere: http://www.the-cr...

Hi,
tested on my Mac and a linux cluster.
It's looking good.
Thanks
