Dear Comsol community,
I have been working with 3D Comsol simulations using the Laminar flow module. I computed the divergence of the 3D velocity field 
and the values are of the order of 
.
However, I would like to reduce these values even more because I need that my velocity field satifies the incompressibility condition with a fair degree of precision. Is there a way to do it? In my view, the only solution is to increase the resolution of the mesh, but I would like to hear your opinions.
Thank you for your help.
Best regards,
