Setting momentum source for periodic calculation
 
Hi!

I would like to investigate fully developped flow through a pipe bundle. I would like to perform it by using periodic boundary condition, but I now the mass flow, not the pressure drop. How to set the momentum source [Pa/m]?

Iteratively!

Hi Robin,

What do you mean by saying iteratively? Will you please explain in little bit detail.

Thanks, Swapnil

The momentum source will allow you to specify the pressure drop. However, to match the mass flow you will have to set your momentum source, check the mass flow you get, then tweak the momentum source until you get the mass flow you want.
