Coupled chtMultiRegion boundary condition

JSalami · April 2, 2021, 01:39

Dear friends,

I am using the chtMultiRegionFoam solver with an added volume vector field called "A" (the magnetic vector potential).

This field should simply be continuous between the solid and the fluid, so the boundary value should be a simple interpolation between the cells straddling the face.

What kind of boundary condition in OpenFOAM would help achieve this? I looked at mapped and mappedFixed but no luck so far.

Any suggestions would be greatly appreciated.

Maybe compressible::turbulentTemperatureCoupledBaffleMix ed can be a start

Thanks for your response, shibi.
I've looked into that before since I use it for heat and other fields but it only supports scalar quantities, unfortunately. In addition, it is kind of overkill since I don't really need a mixed-boundary condition.
I thought I would ask since it seemed pretty simple and there was probably some pre-existing boundary condition for that. But perhaps the only way to do it is a new boundary condition...

Hi, JSalami.
I met the same problem with you, and can you share me the solution to this problem?
thanks.
