ParallelUtils error

Hi, I am trying to compile Elmer with the Intel compiler. I am getting this error with ParallelUtils.f90 ParallelUtils.f90(427): error #8378: Pointer array is not contiguous unless it is declared CONTIGUOUS. [TMPXVEC] Mx => GlobalData % SplittedMatrix % TmpXVec --------------------------------------...

Wrong definition of normals at edges of 3D problem

Hello, I am solving flow in a ring shear device (like a doughnut). Because of symmetry I can solve the flow over a pi/6 angle instead of the whole 2pi. I am using perdiodic bc for in the inlet/outle and I am imposing the velocity at the top of the doughnut (see mesh in first attachment). My problem ...

Problem with temperature using TemperateIceSolver

Hello, I am solving an ice flow problem where I fix the upper temperature of the ice surface and impose a geothermal heat flux at the base. I initialize the temperature throughout the whole 3d domain. Then I solve the heat equation using the TemperateIceSolver and the keywork Convection=Computed so ...

How to call a solver only once at beginning of run

Hi, I need to create a new solver to initialize a temperature field. This initialization needs information from a solver which is part of ElmerIce (FlowDepthSolver). I call the new solver after FlowDepthSolver but it needs to be run only once at the beginning of the run. Is there a keyword for Exec ...

Re: Periodic BC not finding target boundary

Hi Peter, I have tried the problem with the heat equation only and it seems to work fine with the periodic BC. Attached the sif file (works with the coarse mesh sent earlier). Removing the periodic BC for Temperature yields slightly different values of temperature on the inlet and outlet hence I con...

Re: Periodic BC not finding target boundary

Hi Peter,

I will try the periodic problem with the heat equation.
I am away for the next 3 weeks so this will take some time. May be Juha can have a look at the problem in the mean time.

Best,

Denis

Re: Periodic BC not finding target boundary

Hi Peter,
The problem still must lie with the periodic bc. Removing the periodic bc and applying an inlet velocity (nothing at the outlet) is solved without any problem by Elmer (see attached sif file).
Thanks for your help.

Re: Periodic BC not finding target boundary

Hi Peter, Thanks for fixing some of the issues with the periodic BC. However, it looks like some periodic nodes are not where they should be as I am getting this warning message: WARNING:: GlobalToLocal: Node may be out of element rst 2.77008310267920339E-005 -2.50000000136842826E-005 -5.00000000278...

Periodic BC not finding target boundary

Hi Peter, I am still unable to get the periodic bc to work correctly on a piece of a cylinder. It seems that the periodic bc is not finding the target boundary and thus does not apply the periodic bc. Attached is a coarse mesh version of the problem with the sif file. Any help appreciated. Maybe my ...

Re: ListGetInteger error in Periodic BC

Hi Peter, I've corrected the mesh which I think is now OK. However I am still getting the WARNING in the periodic BC. The points between inlet and outlet should be close enough after a rotation of -pi/6. May be I am writing my Periodic BC in my sif file incorrectly. Attached is the sif, the mesh and...
