Has anyone else encountered the same problem?
I know other CFD tools, e.g., OpenFOAM (RheoTool), use log conformation to deal with high Weissenberg numbers. How does COMSOL handle high Weissenberg numbers?
I am trying to model electroosmosis using OB model. My model does not converge, even in a simple straight channel. I believe the issue is not related to the mesh or solver configuration.
