Free surface periodic boundary conditions

Hi, I want to apply periodic boundary conditions on a tilted slab (the ISMIP-HOM A experiment). Some years ago it was recommended to tilt the forces instead of the domain since there was some problem with free surface periodic boundary conditions. I was just wondering if this is still the case? Best...

Re: Output viscosity

Hi,

I see I forgot to answer this. Your solution worked! :)

static load balancing, ElmerGrid?

Hi, I'm partitioning a mesh (called coarse2) for a parallell run. Using ElmerGrid 2 2 coarse2 -metis 5 2 i end up with a mesh with 5 partitions with approximately the same number of nodes in each partition. Is there an easy way to add weights (expressing the work load) to the nodes, so that each par...

Output viscosity

Hi, Is there an easy way of outputting the viscosity (e.g. in a vtu file) when using Glens flow law? I tried using "Save Materials" saving the "Viscosity" (sif below) but to no surprise it only outputs the constant going into Glens flow law (called 'Viscosity' ). Thanks, Josefin ...

Re: Iterative Solver Internal Settings

Hej Peter,

Yey! Thanks a lot, using CRS_SortMatrix afterwards solved it! :D

Cheers,

Re: Iterative Solver Internal Settings

It must have something to do with the CRS_Transpose, since if I exhange AT = A AT = CRS_Transpose(AT) in the code I posted originally to just AT = A it works, but if I change it to AT = A AT = CRS_Transpose(AT) AT = CRS_Transpose(AT) It does not work. I also tried using CALL List_toCRSMatrix(AT) bef...

Re: Iterative Solver Internal Settings

Hi Franz,

You're right I probably pointed back and forth a big too much :) I could also just set AT = CRS_Transpose(A) directly (although I do need to allocate AT first)

I don't believe this is the problem though, since it works perfectly fine to solve with a direct solver :/

Best,

Iterative Solver Internal Settings

Hi, I'm doing ice sheet modeling, and am modifying/adding stuff to some old version of a FlowSolver routine, (so where Au=b is solved, describing the Stokes equations). I'm solving a dual problem, i.e. I'm solving A^T x=f, where A^T is the transpose of A. This works fine if I'm using a direct solver...
