Hello,
I am Daniel, student of Industrial Engineering and I am new in this topic. I am developing a program in Matlab in order to solve the fluid flow in a curved channel.

The characteristics of my fluid are: incompressible viscous and FVM(Finite Volume Method) for the discretization. I have some doubts because I generated a structured mesh but the problem is how to apply the governing Navier-Stokes equations to the program. I don't know how to express it in the code. I would like to apply upwind method and central difference method.
I checked some different programs to understand how to do it but I don't know for example how "kron" function works.

Thanks in advance,
Daniel
