一、前言在求解不稳定温度场的数值解法中,以差分法和有限元法较为通用。但对二维、三维的问题来说,与差分法相比较,有限元法有如下优点:(1)易于适应各种形状的边界。(2)便于处理非均匀、各向异性的情况。
I. Introduction In the numerical solution of the unstable temperature field, the difference method and the finite element method are more common. However, the two-dimensional and three-dimensional problems, compared with the difference method, the finite element method has the following advantages: (1) easy to adapt to various shapes of the border. (2) easy to deal with non-uniform, anisotropic situation.
