Dear all,
I'm new to openFOAM trying to simulate fluid flow in microchannel.
I want to use temperature jump boundary condition on walls for my case in buoyantBoussinesqSimpleFoam. This boundary condition called smoluchowskiJumpT is used in rhoCentralFoam solver.
How can I implement this boundary condition in buoyantBoussinesqSimpleFoam? Any help would be appreciated.

Thanks in advance
hoseinhd

Well, you could compile the BC together with bouyantBoussinesqSimpleFoam. However, as this condition was designed for a compressible solver, there might be some additional coding to get through.
A more straight forward way would be to use a programmable boundary condition like

codedFixedValue
codedFxedGradient
groovyBC from swak4Foam

Cheers

Fabian
