Elmer Discussion Forum

Hi I am dealing with a couple problem in which two different physical processe have different timescales. First is a Glaciological problem which involve a time consuming solver over timesteps of a year (more or less). The coupled problem is an hydrological one in which the timestep should be a lot s...

Hi Franz

Thanks for the tip, vtk file works well for me.

Hi

It would probably be easier to get the BC_ID's directly in ResultOutputSolver and dispatching it with the other variables. I will get a better look at this option tomorrow.

Hi

My first thought were to pick directly the nodeindexes of BC I am interested in in the mesh.boundary file and to create a selection in paraview. But I don't know anything in Python to write the needed macro. So If the BC indexes could be saved in the vtu file this would be perfect.

Hi

I was fearing this answer. In fact I also want to be abble to see the body of my material so your solution does not seem to fit (Or could I run two ResultOutput solver, one for the boundary and one for the all geometry).

Hi Peter

I see the point of your answer but I don't see how to access to the permutation vector in paraview.

Slice filter will only work on a flat surface which is not the usual for my geometries. The "extract surface" work well when coupled to a "clip" filter to get rid of top and side surfaces but it is still not perfect, I will see if paraview users have more ideas.

Thanks

Hi I am working on a 2D plan problem which is delt by Elmer as the boundary condition of a larger 3D computation. I would be glad to get only this boundary when post processing my data with paraview. So, do you know if it is possible to extract only one boundary from the general geometry in paraview...

Hi I was wondering if it was possible to apply a spatialy variable logical condition using Matc function. The code I am currently using seems to fail to fix the condition : Open Pipe = Variable coordinate 2 Logical Matc "if(tx>=400) TRUE else FALSE" Is that failure just a syntax issue or s...
