a composite boundary condition

ywem · February 20, 2019, 00:30

Dear Foamers,
Does anyone know how to implement the following boundary conditions between two domains in an OpenFOAM case?
Phi1=Phi2
mu1*d Ph1 / d n = mu2* d Phi2 / d n
here n is the normal direction.

you can have a look on the implementation of the turbulentTemperatureCoupledBaffleMixedFvPatchScala rField described in https://openfoamwiki.net/index.php/ChtMultiRegionFoam. I guess you want to achieve something similar

Dear Michael,
Thank you for your reply. That's really helpful. I will try to understand them.
