Electromagnetic Solver for OpenFOAM

lkh · September 9, 2009, 07:51

Hallo,

I plan to simulate electromagnetic wave propagation based on Maxwells equations. Can anybody tell me if there is a solver in OpenFOAM suitable for such problems?

Best regards

goes somehow in the direction you want to use OF for

Hi, I tried to run the rodFoam solver but ended up in the error as follows:
Create time

Create mesh for time = 0

Reading transportProperties

Reading field sigma

Reading field ElPot

Reading field A

Calculating magnetic field B

Calculate electrical current density Je

Any help in this regard is much appreciated.

Sooner or later someone will read this thread about "modelling electromagnetics using OpenFOAM".

My advice - if you have simple electromagnetic problem (basic geometry, single region) then you can do it!

If your problem is complex one (geometry, multi-regions) then try Elmer FEM + OpenFOAM : http://eof-library.com

Dzhordzhs thanks!

"Sooner or later" was about two and a half years later, but your advice was very helpful. Elmer plus OpenFoam was exactly what I needed for some capacitance design questions I've been working on.
