Hello Comsol users,
I hope you could me with a that I'm currently working on. i have successfully model a laminar flow of fluid inside a flow chamber. the chamber is in mm scale. now i want to just model the fluid flow locally , about an area of 500x500 micrometer within the chamber. i spent a lot of time getting lost, trying to link the laminar flow of the submodel with the full chamber model, but never successful. in the study step, the error always comes as " undefined variable spf.U , geom2".
could anyone please help me with the steps of submodeling laminar flow? all help is appreciated!

Hi Vina, could you attach a test copy of your model? Maybe we can look and help out.
