Hi, Nagi Elabbasi,

I have tried FSI model. But there is a problem bothering me.
I apply the "Inlet". If the pressure is very small (just 0.009 psi), it will have a result. But if the pressure is a little bit large (0.01 psi), it will have an error. I also try the "Vacuum Pump", but it has the same problem.

Segregated group 2
Attempt to evaluate real square root of negative number.
-Function: sqrt
Failed to evaluate expression
