Hello world.

I'm trying to simulate the flow in an L-shaped duct.
See the picture attached.

I'm using velocity-inlet and outflow as boundary conditions.
The rest are walls.

Unfortunately the case does not converge.
Residuals are stuck at some level.

On what does the convergence of such a case depend?
Any ideas?
