Hi everybody,
I need to discretize a differential equation. The grid that I am considering has a different grid spacing along the three space directions. That is, hx different than hy and hz. For that purpose, I would like to discretize the differential equation through the Mehrstellenverfahren scheme. The problem is that in all the references that I have found, the equation with the corresponding weights assumes that the grid spacing is the same along each of the three space directions (hx=hx=hx=h). I show you the corresponding equation in the attached file.
I would like to use this scheme in my particular situation. Does someone know how this equation would look like?
Thank you very much in advance!
Miquel
