Elmer-Ice in Linux binaries

Hi,

It seems that Elmer-Ice is not included anymore in the pre-compiled binaries for linux ? Could you check ?

Thanks,
Adrien

Re: Semi-lagrangian with particule tracking

Hi, So I could not properly fix the issue. For now, I just did a little hack for limiting the number of iteration in the LocateParticle subroutine since the function ChangeParticlePartition never return zero in my case. See line 4288 in ParticleUtils.F90. This allows the solver to run but some littl...

Re: Semi-lagrangian with particule tracking

Hi, I tried the different modes but this does not seem to solve the issue... It seems that the solver is looping because some particles should be deleted from the partition but in fact are not deleted. The ChangeParticlePartition is looping on this : ChangeParticlePartition: Sending particles among ...

Re: Semi-lagrangian with particule tracking

Hello Rich, Thanks a lot for your answer. Attached the serial version which is working. To create the partition i simply used the command : ElmerGrid 2 2 taco3D -autoclean -metis 4 where taco3D is an existing serial mesh. I tried different things to makes the partition but the problem remains the sa...

Semi-lagrangian with particule tracking

Hello, I am trying to use the semi-Lagrangian solver to advect a variable while modeling ice-flow. My setup works fine in serial but in parallel the solver got stuck (no error or crash but infinite loop). It seems that the issue come from the ChangeParticulePartition routine or the LocateParticule r...

Re: Enthalpy Thermomechanical Coupling of "Test Glacier"

Hi Andrew, Sorry for late reply. I think that the issue come from the fact that you do unit conversion in material : Enthalpy Density = real #910.0 / (1.0e6*yearinsec^2) ! [kg m-3] --> [MPa a2 m-2] Enthalpy Heat Diffusivity = real #(2.1/2050.0) * (1.0e6*yearinsec^-1) ! [kg m-1 s-1] --> [MPa a] Entha...

Re: Enthalpy Thermomechanical Coupling of "Test Glacier"

Hi Andrew, Everything seems correct to me. However if you solve the stoke solver with the "power law" viscosity like you do, you are not computing the viscosity as a function of temperature anymore, it could lead to different result then. There is no issue with using the Glen viscosity whe...
