Elmer Discussion Forum

Hello Kevin! Indeed, I used the k-epsilon viscosity model when I simulated with the Boussinesq approach, and it certainly helped.

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...
