Mass flow inlet BC
Hey guys,

does anybody know how I can apply a mass flow inlet boundary condition?

Cheers, Fabian

have a look at the U-boundary-file of the tutorial: rhoPimpleFoam/angledDuct
The boundary condition is named flowRateInletVelocity...

Hi Marco,

thanks for the hint. I will try it out.

Cheers, Fabian

Is flowRateInletVelocity restricted to certain solvers?
I would like to use it for dieselFoam and reactingFoam.

Is the unit kg/sec?

Hi Rishi,

I don't know if it is restricted, I just tried to use it with simpleFoam.
However, its not a mass flow bc but a volume flow bc. So the unit is m^3/s .
