The finite element analysis of three-dimensional steady-state convection-diffusion equation is given by using 4-node tetrahedral elements and 8-node hexahedral elements.
采用四结点四面体单元和八结点六面体等参数单元进行三维定常对流扩散方程的有限元分析。

The convergence of hexahedral isoparametric element of form (2) is analysed in this paper, then the optical interpolation error estimation of it is obtained.
研究了(2)型等参六面体元，分析了其收敛性并给出了最优插值误差估计。
