GebhardtFactors binary

Hi Elmer team, I've tried the GebhardtFactors program (just for testing its funcionality) with different meshes (with updated view factors) and correct sif files (tested launching ElmerSolver with same mesh) and I always get a seg fault. What is this binary intended for? Can I use it as a stand-alon...

Re: ElmerGrid creates invalid mesh

Hi, the ElmerGrid output when you convert the mesh into the Elmer mesh.* format says that your original .unv mesh contains a lot of lower dimensional elements (like, for instance, a 1D element in a 3D mesh). You must clean those degenerate elements before loading the mesh, as ElmerGrid with the flag...

Re: Possible Bug in Elmer Heat Solver with Radiation BC

Hi,

try using only the Picard method for the non-linearity, as Newton method may not converge. That is, in your sif file

Code: Select all

  Nonlinear System Newton After Iterations = 20
  Nonlinear System Newton After Tolerance = 1.0e-7

Re: Keyword argument issue by using elmer?

Hi jacklance,

it seems that you missed the proper forum. This Elmer forum is actually for the FEM tool, not the software glue http://elmer.sourceforge.net/

k-w SST and v2-f turbulence models

Hi, I've searched the sources of the SST k-w and the v2-f solvers (elmerfem rev. 5676) and I have a couple of questions about it's implementation: 1: It seems that no limiter for the kinetic energy production term (to avoid an excessive production in stagnation points) has been implemented in any of...

Re: Interpolation onto reference grid for parallel cases

Hi, searching the repository I've found some revisions of the ResultToResult standalone program implemented after this post which mention the addition of parallel capabilities, but AFAIK there's no documentation neither on the serial nor parallel funtionalities. Is this program actually working with...

Re: Extracting Boundaries in Paraview

Hi, Peter, Matthias:

Peter: thank you for the new feature and your quick response (as usual).

Concerning the keyword, I think

Code: Select all

Save Geometry Ids = Logical True
is a better choice.

Re: Extracting Boundaries in Paraview

Hi This would probably be some new DataArray of Int8 type in CellData. Any other ideas? The VTU format definition may be found at http://www.vtk.org/VTK/img/file-formats.pdf -Peter Hi, Peter: though the problem posted by Basile is solved, modestly, I think that it would be nice to have the domain a...

Re: Extracting Boundaries in Paraview

Hi,

perhaps you can filter the surface by its material id, defining a "threshold" filter over the cell data (material ids) in the "selection inspector".
