Comsol does not finish the calculation even though convergence criteria is satisfied

Hi,

I have a rather strange problem with COMOL and hope that anyone can help me.

I am trying to solve a "free and porous media flow" on a 3d geometry. The calculation is not converging very well but it reaches the predefined criteria (<1e-3) after some time. But for some reason, the calculation does not stop at this point, but continues. Is there any reason for this behaviour? And how can I get a result at some point?

Thanks for your help

Best regards
