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,
