Hi,

I am working on two-phase (levelset) problem and I need to define a force and add it to NS equation (Laminar flow). The force is equal to constant * delta* n where delta and n are the delta function and interface normal vector. How can I implement the delta and n at comsol?

Thank you so much in advance,

Regards
