Default Pressure BC

What concentration values should be set at the pressure boundary?

If the value is zero does it affect the solution?

Thanks, Julie

Hi Julie, If you put this boundary far way from the combustion zone, you can probably use the zero gradient assumption for the scalars. Regards Allan

if the flow is going into the computational domain at the pressure boundary, then the situation is similar to inlet boundary condition, and all scalar quantities have to be specified. However, if the flow is going out, then the scalar values you specified will NOT be used by the code.
