Inputing Navier-stokes eq. in to comsol by using PDE

Please login with a confirmed email address before reporting spam

Dear friends,

I want to solve the inviscid flow in comsol for a two phase problem, but by setting viscosity to Zero, there are some problems with convergence. It seems that I should input the inviscid NS equations in to comsol manually.

How can I define the Inviscid NS equations in comsol by using PDE or somthing else??

Best regards,

i'm trying to do the same thing to, i chose to use the "weak form, subdomain" but i don't know how to input my boundaries conditions .. ideas ?

thinks all :)
