Hi,
I tried to simulate a T junction air channel, the intention was to check the venturi effect. but I got problem for the convergence. I tried to change the mesh, add the point pressure contraint, etc. problem is still there.

Could anyone help me on that? Thank you in advance!

Hi,

Change flow type from laminar to turbulent. Air inlet at speed 5 m/s gives Reynols value of 94000 and that is for sure turbulent flow.

Best regards

Tero
