Hi.. i'm new in comsol.. i'm doing 2 d simualation of wind passes through the hill by comsol multiphysics 4.2. May i know, did i need to specify momentum and continuity equation (ux+vy=0 and uux+vuy=-p'(x)+uyy)? because the simulation still get the right result even i didn't insert it.. If the equations is already embedded in the Comsol, may I edit the equations? or at least show the equation? thanks...
