摘要
对一类变系数热传导方程,提出一种新的数值解法.首先使用Crank-Nicolson有限差分格式将给定方程离散为线性代数方程组AU=b,然后用雅可比超松弛迭代法把AU=b转化为U=LU+f形式,最后用蒙特卡罗方法求解代数方程组U=LU+f,得到数值解.算例说明这种方法的有效性.
For a kind of variable coefficient heat conduction equation,a new numerical solution method is proposed.First,the given equation is discretized into linear algebraic equations using the Crank-Nicolson finite difference scheme,and then the Jacobian over-relaxation iteration method is used to transform it into a form,and finally The Monte Carlo method is used to solve the algebraic equations,and the numerical solution is obtained.An example shows the effectiveness of this method.
