I didn't set velocity boundary conditions at all patches. One usually runs into trouble with stupid "continuity errors". The tolerance for continuity error is 10e-8 (refer source code for...

Ok, so this means I have to somehow access total volume flow rate field (say phi_inlet) at the inlet patch from within the simulation and define volume flow rate at outlet1=0.52*phi_inlet and...

Hi Bruno,

Thanks for the quick response.

The flow at the inlet is parabolic.

Basically, I want to divide the inlet flow into 0.52 times at one outlet and 0.48 times at the other outlet....

Continuity error with volume flow split boundary condition

Hi,

I am trying to simulate a case in which a tube with one inlet bifurcates in two outlets. I ran the case with simpleFoam solver by fixing volume flow rate at all outlets(because that is the...
