Fixed Outlet Mass Flux boundary condition?
I read somewhere that Outlet Mass Flux boundary conditions are being discussed in this form... but i did many searches and couldnt find anything.
Basically my question is
Is it possible to set the mass flux at the outlet? If so, what boundary condtions do i have to call??
ie. type FixedOutletMassFlux: ?? (does this exist)
Thanks in advance Foamers!
try flowRateInletVelocity with a negative flowRate. I have never used it this way, but it should work though.
I have indeed tried flowRateVelocityInlet but to no success. Any other options. I am unclear as to why its not working, but it seems that when the inlet velocity goes from positive to negative, the flow direction is still the same...:eek: which completely does not makesense to me! and then when it hits 0, a whole pile of errors come up. And as we all know, debugging openFoam errors are next to impossible.:p
Is it possible to just set the outlet velocity whilst leaving the inlet velocity as an $internalField? I have tried setting outlet velocity but it doesnt seem to work. Is there a different boundary condition that I should be using?
