Incompressible Fluid Flow - Convergence Problem (Boundary?)

What a beautiful summary of a quite possible imagination! Some colour, tooltip info or history info. Simulating is starting to seem like a very artistic process to me and I’m here for it :pinched_fingers:

And as we are here for it. My new convergence problem seems to be the outlet which now looks like this:

I feel like there is something fundamental I am missing so if anybody has seen this or suggestions please let them flow. Its als possible to see the values of certain probe points and there seem to be regions which are more stable than others. Could it be that the area is just too complex because of a lot of sharp edges or would you think it is more of a mesh refinement or boundary condition problem?
