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

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
