Dear OpenFoamers,

I am running a pimpleDyMFoam case. I would like to compute flow rate at the inlet. I included this function object in controlDict. Is there a way to make sure the output is m^3/sec? I only got a value and it is not what I expected.

Any suggestion?

Thanks!

Hi Pei-Ying,

Since the operation is "sum", then the units for "phi" are preserved. Knowing the units of "phi" should then simply be a matter of looking at the units of the respective field file "phi" in the time snapshot folders.
I ran the tutorial "incompressible/pimpleDyMFoam/movingCone" and got this in "0.003/phi":

dimensions      [0 3 -1 0 0 0 0];

Best regards,
Bruno

Thanks a lot Bruno!
