Hello, I'm implementing a SIMPLE code on Matlab but the idea is that the discretization of each component is done by matrixes equations (for each control volume) so when I want to change the discretization of the code I just need to change those matrix. For instance, in the momentum equation I'd need a matrix for the convective term, one for the diffusive term and other for the pressure term (steady state). How could I built those matrixes for each control volume? (Let's imagine that I want central differences)
Thank you very much
