If anyone feels this would be better kept outside the main repository, it could be added to the FEniCSx tutorial instead if @jorgensd is happy |

Does \nu actually get used in the discretisation?
There was a problem hiding this comment.
The discretisation uses the dimensionless form, where \nu is incorporated into the Reynolds number. I'll make this clearer

This PR adds a divergence conforming discontinuous Galerkin demo for the Navier-Stokes equations.
It demonstrates:
As far as I'm aware, none of the other demos demonstrate the above functionality.
I still need to so some tidying. Any feedback would be much appreciated.
