We have an exciting announcement about badges coming in May 2025. Until then, we will temporarily stop issuing new badges for course completions and certifications. However, all completions will be recorded and fulfilled after May 2025.

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.
