Im trying to simulate a radiator in which water is flowing through copper tubes and the tubes are surrounded bby fins to transfer the heat. When computing I get the following error:
Matrix has zero on diagonal for the SSOR update submatrix in the Vanka algorithm. In Velocity u, Pressure p: There was an error message from the linear solver. Maximum number of intermediate iterations reached. Returned solution is not converged. Not all parameter steps returned
I am using laminar flow and heat transfer in fluids interfaces.
