How to apply Neumann and Dirichlet's BC

I am trying to simulate flow across a cylinder in General PDE form. The governing equations are Euler's equation for Mach No. = 1. I have converted these equations in the COMSOL form to be substituted in subdomain settings. And tried simulating the flow. But the problem I am facing is in setting the boundary conditions.
I have a rectangular flow field and a cylinder placed in it. A 2D geometry. Two boundaries are inlet and outlet and rest all are solid wall boundaries with no slip condition. But expressing these in COMSOL, is getting a bit difficult for me.
I would appreciate any kind of help in this regard. Looking forward for your replies.
Thank you,
Anuurag
