Chorin's Projection Method for Finite Volume
Hello,
I am attempting to implement Chorin's projection method using the finitevolume method in Cartesian coordinates. I am having difficulty constructing the poisson equation for the pressure. When I attempt the define the div(grad P) it appears that I need to reference at least two cells outside of the computational domain. Does this sound right? Can anyone direct me to a text or example? Thanks, Scott
