ajhunte is on a distinguished road
I am currently running a simulation with only one inlet and one outlet. I am getting kind of wonky data in the sense that the mass flow rate at the outlet is 45% less than that at the inlet. Is there a good reason that this should happen?

ABOUT MY SYSTEM:

Inlet --->Pipe ---> Smaller Diameter Pipe ---->Original Diameter Pipe----> Split in the system ---> recombine pipe ----> outlet

the split in the system is basically two pipes with equal diameter that form a circle. water goes in, splits, and then rejoins at the opposite side of the circle.

oj.bulmer will become famous soon enough
The only reason can be that it hasn't converged
How do the mass imbalances look like?
