Hello dynamic mesh experts,
I am looking for a boundary condition for the U field of the rhoPimpleDyMFoam solver. This bc should fix the mass flow rate that is passing the moving boundary patches of an elastic body. The deformation of the elastic body is calculated separately. So, you can think of a sponge with known dynamic surface deformation, which gets a compressible fluid pumped in or out at a given rate at each surface location. Does such a bc exist? Or is it possible to specify a flag for the flowInletVelocity such that it operates on fluxes relative to the mesh motion instead of absolute fluxes? Greetings Olaf |
