ONE-SIDED DIFFERENCE APPROXIMATIONS -- CFD Online Discussion Forums

Andy Guest Posts: n/a	Does anyone have a referrence(s) for the approximation of first-order derivatives on a non-uniform (graded) mesh. In particular, I am after a first-order, second-order and third-order one-sided difference suitable for a non-uniform mesh. The one-sided difference approximations will be used to approximate velocity gradients at the wall and hence wall shear stresses. Thanks Andy.
