Fluid to fluid boundary conditions

Hello openFOAMers,
I am currently working with catalytic combustion in a fluid region coinciding in a larger flow domain, using a solver which combines the reactingFoam solver and chtMultiRegionSimpleFoam solver. Therefore, I decomposed the fluid region into reacting and non reacting regions. This approach results in an issue with the boundary conditions at the connecting patches, for both velocity and species. For the temperature field the boundary condition for the connecting patch is: Code:
compressible::turbulentTemperatureCoupledBaffleMixed; Any suggestions for a equivalent velocity boundary condition or another solution to the boundary condition issue? I read another post working with a similar issue: chtMultiRegionFoam BC for fluid-fluid zones being focused on specie distribution, which uses a converted boundary condition of the temperature boundary condition: Code:
compressible::turbulentTemperatureCoupledBaffleMixed; I have attached both a test case for two connected fluid regions using the chtMultiRegionSimpleFoam solver, and the custom boundary condition resulting in a compilation error. Hope anyone has some input. |
