摘要：
In this paper, the solution of a 3-D diffusion problem of the first kind boundary condition with the Method of Finite Element is carried out. Elements of tetrahedrons are divided and the resulted algebraic equations are solved. Compared with the Method of Finite Difference, it can obtain more accurate results with less calculations; especially for the cases where irregular boundaries are involved.
