Hi, I'm new to OpenFOAM. I'm trying to model the flow of a mixture of liquids in a cylindrical shape with interFoam. When I try running the solver, I get the error below. I set up the shape to be enclosed by walls on all sides (where one of the walls rotates). I don't have an inflow or outflow that I'm aware of. I don't understand why I'm getting this error. Any ideas?

Please check the velocity boundary conditions and/or run potentialFoam to initialise the outflow.
