Pressure at inlet in OpenFoam
 

Dear Foammers,

I have to introduce a pressure at inlet. I know nothing about the velocity in inlet.
Does any foammer know how I can include this in the boundary condition files.

May be I have to use the pressureInlet. How I can use this condition? Where? In the velocity boundary condition file? In the pressure boundary condition file?

Any suggest will be very appreciate.

Thanks in advance,
Elisenda

first approximation can be fixedValue for pressure and for velocity u can use one of these three conditions :
zeroGradient
pressureInletVelocity
pressureDirectedInletVelocity
