Elmer Discussion Forum

Hi, Elmer community! I've been using Elmer for a year or less and it seems to be a quite competitive tool for FEM simulations. Until now I've just used ("correctly") the Heat and Stat Current Solvers for a metal bar which cools through natural convection (as a boundary condition) and is he...

Hi again! I resolved the problem. I don't know if it's version incompatibility or something like that but I added to the file PstreamGlobals.H in /usr/lib/openfoam/openfoam2212/src/Pstream/mpi inside namespace PstreamGlobals { ... } the line extern MPI_Comm MPI_COMM_FOAM; and it worked. But now I ha...

A few days ago, there was a pull request with fixes for OF v9 and v10. I merged them just now. I'm using openfoam2212, I don't know if it's the same version as the ones you mention, but just in case I've run sudo apt-get update && sudo apt-get upgrade However, I resolved my problem with . /...

Hi! I don't know if this is the correct place to ask about my problem, please feel free to redirect me to somewhere else if this is not the place. I am trying to install EOF-Library on WSL with Ubuntu-20.04.5 LTS following the "Manual Installation" instructions on https://github.com/jvence...

Thank you all! I applied all your recommendations and played a bit with convergences tolerances and max. iterations and finally arrived at reasonable results.

Cheers,
Matias.

Hi everyone! I'm making good progress with Elmer (GUI and non-GUI) but I encountered something I don't quite understand. Currently, I'm using Python to run ElmerSolver with little variations of a case.sif. This case is simple, a box of 1x1x1 m3, Steady-State, with 4 sides walls with BC at 297 K (Hea...

This paper has some direct comparison with Comsol https://www.researchgate.net/publication/335771019_Microwave_heating_of_water_in_a_rectangular_waveguide_Validating_EOF-Library_against_COMSOL_multiphysics_and_existing_numerical_studies Thank you, Peter! That paper is precisely what I was looking f...

Thank you! I’ll take a peek on those links.

Hi everyone! I'm using this software to simulate a thermoelectric transient system of a high-voltage isolator to make virtual testing of a temperature-rise test of this device. We would like to have our results with their uncertainties so we can compare them with experimental ones. I've read that th...

Hi everyone! As you recommended, I added Air to the problem, but new questions arose. Now I have a box of air surrounding a copper sheet, I'll attach the .SIF file for you to check and this is the mesh: https://drive.google.com/file/d/1jRlJMuSOUay7eIWbWYRt2DPyOrni6y4R/view?usp=sharing I added two eq...
