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. |
