本文推导了使用常单元和线性单元时矩阵元素的解析表还式,从而避免了数值积分。
This paper derives the analytical formulas for elements of the matrices using constant and linear elements Therefore, the numerical integral can be avoided.
我们知道现在要积分面积元素,那就对dxdy积分。
So, we know that we want to integrate just the area element, let's say, dx dy over the origin inside the ellipse.
从应用角度看就是最终线性方程组每一元素均为显式表达,没有数值积分。
From the point view of applications, the matrix element of the involved linear system of equations is an explicit expression without numerical integration.
