Default Pressure-based mutiblock method
Posts: n/a

I'm trying to solve with the pressure-based composite grid method for Navier-Stokes equations some multiconnected cases as the channel with two baffles simulated by Wright and Shyy. I'm using a Neumann internal boundary condition for the pressure correction map. In order to avoid the pressure jumps that appair in some interfaces, Wright and Shyy suggest to force the normal momentum balance between each control volume of this interfaces. We have donne it but it doesn't works.

Have I understood correctly what Wright and Shyy suggest???

Is there other ways to avoid this pressure jumps in multiconnected grids???
