BCS for SIMPLE
 
In pressure correction equation for the SIMPLE algorithm, BCs when normal velocity or pressure on the boundary are known are easy to implement. Alternatively, at the outlet, one can specify that properties do not vary in streamwise direction. How can one specify in that case the BCs for the pressure correction equation??. Thanks for your comments.

Re: BCS for SIMPLE
 
Often , for a outlet in incompressible flow, the pressure is imposed. i.e. The variation of pressure is zero.
