So figuratively, I'm trying to win a nuclear war with a stick. :rofl: I did not take any course in PDEs, I just self-studied some of them, and now I'm toast. :rofl:(adsbygoogle = window.adsbygoogle || []).push({});

First, please feel free to hurl rocks at me if my simplification is incorrect:

Second, how do you discretize ∂^{2}u/(∂x∂y)? Is it:

(u_{x+1,y}- 2u_{x,y}+ u_{x-1,y})(u_{x,y+1}- 2u_{x,y}+ u_{x,y-1})/((x_{i+1}- x_{i})(y_{i+1}- y_{i}))

I might have a few more questions after this. Sorry if everything I'm saying is incorrect, please don't be harsh. I'm telling the truth when I say that we didn't cover this in our numerical methods class and I didn't take a PDE course. Thanks!
