Hi,

Where can I find the expression of the central difference approximation of the first and second derrivative (spatial) for a NON uniform grid?

Hi,
I think the derivation in the case of non uniform grid should be similar as in the case of the uniform grid.

Write down your differential equation, I will try to help you.
