WebSep 2, 2012 · FVM is easier to formulate, and there is a large and long volume of research using it. Another reason for its larger spread is conformism of the CFD community. There is another point. the FVM is conservative by constuction, while the FEM is not necessarily so. There is a debate how important this property is for better accuracy. Web6. What is the advantage of the FEM over finite difference (FDM) and finite volume (FVM) methods? The major advantages of the FEM over FDM and FVM are its built-in abilities to handle unstructured meshes, a rich family of element choices, and natural handling of boundary conditions (especially flux relations).
