Hello all,

I want to model a membrane separation process in OpenFOAM, but I cannot find a suitable way to do this :S. At this moment I have icoFoam extended with solute transport, the outlet of the reactor however should be permeable for certain solutes and others should be retained.

I guess chtMultiRegionFoam could be a possible solution, but I would much more like to implement a new boundary condition which is regulating the outflow of solutes depending on a value in a self-made dictionary.

Any suggestions, tips or tricks?

Thanks in advance!
