Hi,

I would like to solve for magnetic field (Maxwell equation) induced by permanent magnets. Each magnet has different material properties. Hence, I am considering a new solver with multi regions. chtMultiRegionFoam is similar, but, much more complex because it solves both fluid and solid.

Has anyone tried anything similar, ie, one governing equation (vector, not scalar) but, with multiple regions?

Thanks!

Pei

I don't think it should be too hard. I modified chtMultiRegionFoam for a simple diffusion equation (for a scalar) between two regions where the diffusivity changes between the two regions.

Here's my model: multiRegion-chtMultiRegion.tgz

And you can see the basic result here: Integrated conjugate heat transfer solver in OpenFOAM

Thanks a lot benk!

I will study your implementation. Maybe we can write a tutorial on this later.

I can help with a tutorial on this, although I'm still trying to understand chtMultiRegionFoam myself.
