请教有限体积法与有限差分法的区别 (无内容)

Finite difference, finite volume and finite element methods have been used to model the coupled thermal, concentration and fluid flow. Early studies using the finite element method have considered more complex boundary conditions but neglected melt convection. On the other hand, finite difference and finite volume models have routinely included the melt convection. However, the irregularity in the domain poses problems for finite difference and finite volume models. As a result, most simulations using the finite difference/volume methods assume a regular geometry and a flat interface |
