Ensure divergence-free flow in COMSOL

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,

LeninMFR
