Hello,

Just to be sure. Can anyone confirm that the impermeability of solid boundaries (and vertical structure) is done by a weak formulation ?

Just to know, is it hardcoded or that can be modified by keywords or .cli ?

Hello,

Exactly, this guarantees an exact mass conservation even if U.N is not exactly 0 in the results. You cannot modify this, the only other possibility would be a boundary condition 2 0 0 that sets a no slip condition.

With best regards,
