How can i set PISO algorithm on matlab?

Hi,

I'm trying to set PISO algorithm on matlab for simulating incompressible flow.

How can i set PISO algorithm?

I already tried that code..but it doens't work..

That is all I could find.

Mathworks does not offer a piso function.

I'm already facing the same problem. I implemented everything for PISO algorithm but the problem which im currently facing is how to deal with the source term of the pressure correction equation at the boundary for open channel flows. However, it works really fine for fully drichlet boundary conditions problems e.g, Driven Cavity. Also, i extended this code for PIMPLE algorithm but still facing the same problem with the inflow and outflow boundary conditions for the transient flow.
