By default, CFX solves for the Navier Stokes equations including viscous terms.The governing equations for inviscid flow, also known as Euler equations, are obtained by discarding the viscous terms from the Navier-Stokes equations. To do this: 1. Set a very low Dynamic Viscosity value, say, 1e-12 kg/m/s, 2. Activate the 'laminar' turbulence model option. 3. Set the 'Free Slip Wall' option at all walls.

I tried this way(1,2 and 3) in CFX for an annular cascade flow, but it didn't give me the right streamline distributions on the endwall. So I used Fluent and got the right results.
