Steady State, Inviscid, Incompressible flow

Just wondering if anyone has implemented this as a custom equation. I took my last FEM class 30 years ago, so I'm a little fuzzy on implementation and the notation in FEATool.

Equations on the 2nd page of this link are what I'm looking to implement.

That should simply be the Navier-Stokes equations, less the viscous terms. You can add a Navier-Stokes physics mode and use the "edit" button in the Subdomain Settings dialog box to change the equations, and delete the viscous terms (with 2nd derivatives ux_x etc). Note that the form in FEATool has the momentum equations multiplied with rho, while in the paper divided, but they should be equivalent (for constant rho).
