I am currently just running a normal 3D incompressible flow problem in COMSOL 3, and end up with the following error:(adsbygoogle = window.adsbygoogle || []).push({});

Error:

Time 0:

Error in residual computation:

The_relative_error_is_greater_than_the_relative_tolerance

For the direct solver.

Last time step is not converged.

How do I go about resolving this issue?

Thanks.
