The simulation should calculate with a membrane as a wall (only permeable for certain substances).

There is currently no pre-defined membrane boundary conditions. What you probably want is to define a Flux (Neumann) boundary condition where the magnitude of the Flux depends on a combination of concentrations etc. If you know specifically how the PDE of your membrane boundary condition looks like it would likely not be that hard to define.

Yes but it's hard to define if you using multibody.. but with FEA its impossible to use multibody: like i showed in another thread "https://i.imgur.com/FuCFpwI.png"

And how to use a part with more than one subdomains (& Boundarylayer) in FEA to show a membrane process? A membrane seperate two parts (multibody). In openfoam is it possible.
