自适应网格有限元计算方法，用来求解线性偏微分方程-Adaptive mesh finite element method for solving linear partial differential equations

CALCULIX是一款开源的有限元求解器，它由CGX和CCX两部分构成，其中CGX为有限元前处理部分，CCX为后处理部分负责方程组的求解计算，CCX为CALCULIX的主要功能部分。-CALCULIX is an open source finite element solver, CGX and CCX It consists of two parts, which CGX finite element pre-processing section, CCX partly responsibl
