I try to model a diffusion process in a channel with cross-flow tubes in 3D. Since it is 3D and there are so many cross-tubes, it requires a huge computational cost. That is why I want to solve laminar flow for only one of the cross-tubes and apply the solution to the others. How can I generate repetitive solution domains in COMSOL? I want to repeat the flow solution for cross-tubes and combine the solution with diffusion and main channel flow.
