Hi,

I'm trying to simulate blood flowing inside an irregularly shaped 3D vessel with one inlet and one outlet. The inlet is not normal to x, y or z. For now, I'm running steady state simulations.

I'm using SU2 v 7.0.2 and I started by editing the cfg file from a 2D channel example. In my case, I'm prescribing the an inlet velocity profile from a file.

I'm reaching convergence in a few iterations, but I'm not convinced by the results. In particular, I don't understand:
- why the INC_VELOCITY_INIT value will affect the computed velocity field so much,
- how to properly set the CFL number,
- why the velocity profile doesn't seem to fully develop to a parabolic-like profile,
- if there is a way to strongly impose the inlet boundary condition.


Many thanks.
