Hi Foamers,

I'm working on a simple VENTURI pipe simulation. I started with a single straight pipe to make sure I was going on the good way. I started with laminar model but the simulation crashed, I understood the case was intrinsically turbulent so after setting up the turbulence model everything worked fine. After this I thought it was ok to go ahead with a single T pipe (no venturi yet) to make sure the mesh was good, etc. I don't understand why I'm having convergence problems since I have run much more complex geometry simulations with any problem.

In attached the full case already run and with the residuals written: https://drive.google.com/file/d/1IYn...ew?usp=sharing
