Discretization Techniques Overview by Sheng Wang is a document available to read on EtoBox.

What is Discretization Techniques Overview about?

The document summarizes three common discretization approaches used in computational modeling: finite difference method (FDM), finite element method (FEM), and finite volume method (FVM). FDM solves for point values at grid nodes, FEM solves for weighted basis function coefficients, and FVM solves for cell-averaged values. Each approach results in a system of algebraic equations that is discretized from continuous governing equations. Boundary conditions are handled differently depending on the method.
