Hi,
When I run a computation for my model for laminar flow, comsol returns the error "multigrid sublevel has more degrees of freedom than top level". Does anyone know how I can fix this?
Maybe I should change into another type of iterative solver? ( I don't have any knowledge on what solver suits best for my model)
Or can anyone tell me which parameter to change in order to increase/decrease the degrees of freedom for multigrid level??
Thank you.
