what does mean freeStream or freeStreamPressure type?whats the difference to zeroGradient?
Code:
{ version 2.0; format ascii; class volScalarField; object p; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // dimensions [0 2 -2 0 0 0 0]; internalField uniform 0; boundaryField { inlet { type freestreamPressure; } outlet { type freestreamPressure; }

I have found it in the solver's text.so its derived from inletOutlet.OK.but it has not mentioned that whats the difference between freeStream BC and inletOutletBC.
does anyone know about it? Code:
Description This boundary condition provides a free-stream condition. It is a 'mixed' condition derived from the \c inletOutlet condition, whereby the mode of operation switches between fixed (free stream) value and zero gradient based on the sign of the flux.
