Hello everyone,

I am simulating a centrifugal fan (air) and when my inlet is "Mass Flow Inlet", the Initialization always gives me ZEROS and I can't start my simulation. Do you have any suggestions?

Best regards,

Best regards,

What initialisation are you using. Try standard with compute from inlet and double check the values.

If you want better initialisation, try FMG(but you wouldn't need it tbh)

Hi everyone.

It has been my mistake and FLUENT was ok


The problem was that Mass Flow Rate accepts XYZ direction. And in my case, the direction was wrong (tangent of the inlet). Hence, the initialization values were all zero.
