Boundary condition

Hi,

I want to implement a BC's to my reactor, where i know pressure and velocity only at the inlet. How i should specify pressure and velocity BC at outlet? I am using reactingFoam as a solver. Please guide me.

Hi ivkash,

I have think you should set up at outlet for velocity is Neumann condition (zeroGradient) and for pressure is fixedValue, with the fixed variable, guess you can determine in your case. I the better way, the user guide or tutorial in your folder.

Best Regards,
