ok, I'll try to see if there is a relation between all this!

So I remeshed and I got an orthogonal quality of 0.15, which seems good. So I restarted the static calculation but the residual continuity seems to have stabilized even though I asked for a residual value of 1e-4 and it stabilizes before. Should I exploit this result? Is there anything else that can be modified so that the residual continuity converges to the imposed value?said "Take a look at the flow field. I would focus on immediately downstream of the valve and also on the walk." How? It's a compressible gaz (so ideal gaz)
