About this document
FDM, FEM, and FVM Differences Explained by sanga69 is a document available to read on EtoBox.
The three main numerical methods used in computational fluid dynamics are the finite difference method (FDM), finite element method (FEM), and finite volume method (FVM). FDM solves fluid flow problems by approximating derivatives with finite differences on a discretized grid, FEM uses variational methods to find approximate solutions to boundary value problems, and FVM discretizes the governing equations into finite control volumes to solve problems.
