Web$\begingroup$ Yeah I've became aware that FEM is also used in CFD. I would say that I see FEM used more in CFD than I see FVM used in elasticity. However, I have seen quite a … WebFEM vs FVM? In principle, one could model multiphysics problems within a single framework by using either FEM or FVM. In practice, FEM dominates in structural mechanics and electromagnetics, while FVM is preferred for computational fluid dynamics (CFD). WebFVM has the relative advantage of being mathematically straightforward (particularly over some of the more abstruse versions of FEM) and in particular is excellent for problems in which quantity conservation is vital.
