Elmer Discussion Forum

Hi all, Recently , I tried to use adaptive meshing in 3D, with the mesh exported from Salome 8.5.0. The following error was encountered during Elmer solver run: DefUtils::DefaultDirichletBCs: Setting Dirichlet boundary conditions DefUtils::DefaultDirichletBCs: Dirichlet boundary conditions set CRS_I...

Hi Kumar,
I too obtained segmentation fault when i activate porous media: I will seek the work around and reply you back.

I would try to do the rotation in ParaView. There is a "rotational extrusion" filter which you could check out (I have never used it myself, though). If you have difficulties, the ParaView mailing list and/or their forum is there to help. To get the values into Elmer, you could store them in an ASC...

For finite element analysis (FEA) of temperature and composition dependent materials properties of metals and alloys in Elmer multiphysics software, CALPHAD technique can be coupled with the FEA. Some useful resources for CALPHAD method are: 1. http://www.calphad.com/calphad_method.html 2. http://ww...

Hi, A good website for using ubuntu in Oracle virtual box within Windows: https://www.lifewire.com/run-ubuntu-within-windows-virtualbox-2202098 I can install Elmer within Ubuntu environment inside the virtual box. The computer we are using must have enough space and fast enough to run the virtual bo...

So then I guess the final output units will be kg/s, since SaveScalar integrates over line (in 2D) or surface (in 3D). Neus Neus, 1. The expression D* grad_C or D*dC/dx is the mathematical form of flux, that can be assumed for unit by putting the SI units of D, C and x. It is not integrated directl...

Mark,
Thanks for the substantiated reply to Matthias' query.
Would you please enumerate the CPU times (for your parallel run) in the described CFD simulation (with the number of mesh elements, steady state iterations etc.)?


Yours Sincerely,
