线性Poisson-Boltzmann方程的数值模拟

作用：用mortar有限元法求解二维三区域Poisson boltzmann方程。

报告：线性Poisson-Boltzmann方程的数值模拟

文章：A mortar finite element approximation for the linear Poisson-Boltzmann Equation,Applied Mathematics and Compuation,(article in press),2004

程序： matlab代码

入口：用matlab生成的网格，需要三个区域的网格数据 (p1,e1,t1),(p2,e2,t2),(p3,e3,t3)，其中不同区域的网格是独立的，最后通过Mortar条件粘合起来。

出口：得到Poisson-boltzmann方程的数值解

主要子程序：单元刚度矩阵生成myCalstiff.m，Mortar矩阵计算CalMor.m，及主程序调用 [U,z1,z2,z3]=mortarfem1_show(p1,e1,t1,p2,e2,t2,p3,e3,t3)

三区域网格示例

由于把点电荷的作用转化到区域的边界

使得边界上的函数值不连续

有限元解叠加上基本解得到的结果
