Hi,
I have a question about the flowRate in the tutorials squareBend:
for inlet in U it is fixed to 0.5, i suppose its kg/s?
I have done some simple conversion and I get a velocity around 510m/s, am I right? could somebody agree?
Unfortunatly if I put a fixed value of this velocity then rhoSimplecFoam is ending at the 2 iterations!!!

Any suggestion?

Many thanks,
Pierre.

Hi guys,
So i am still trying to understand how it is working, again on the squareBend I have inputed (and configured) a velocity like inlet. I am also using the swak4Foam in order to get the inlet massFlow.
1/ the tutorials case gives around 500m/s velocity and a simulated massFlow around 0.49 kg/s (which correspond to the inlet value)
2/ the new case generated using inlet velocity of 50m/s gives a simulated massFlow of 0.045 kg/s which is consistant

The (may be stupid) question is why I couldn't get a run working with more than 50m/s as inlet velocity?

Please..
Many thanks,
Pierre.

Note: I have attach the case.
