If you do not want to treat explicitly the equation wher the BC enters into, then you have to use ghost points. Therefore, you start at t0 prescribing fold for i=0:N+1 then compute fnew(1) using the...

Sorry to say that I think you have not programmed correctly the BC.s. I give you a very simple 1D example. Consider the domain going from node 1 (x=0) to node N (x=L). Therefore, the periodicity is...

If you are using colocated grid, the things are the same in x and y direction. If the periodicity in one general direction is between node 1 and node N then you have for a general function the links...

Immagine a flux vector fluxes_species(1:N) and the periodicity being between 1 and N and where fluxes_species(i) is at the left side of the components species(i). So the update of the species(1)...
