Please briefly describe the advantages of finite element method and finite difference method.

The finite element method should be based on the difference method.

Finite element method: the physical model is discretized and the grid is irregular, that is, various elements can be mixed and solved without writing equations.

Difference method: the divided grid is regular, and discretizing the equation is a method of replacing differential with multiple differences and replacing differential equation with linear equations.

When studying geology, we should pay attention to the process of analysis and understand the results of analysis. Geology is also a practical engineering field after all. Let those theories study physics and mechanics.
