三维球形域泊松方程的差分方程中自然边界条件的处理

Dealing with Natural Boundary Conditions in Difference Equation of Poisson Equation of Three-Dimensional Spherical Domain

推导了球形域泊松方程的差分格式,比较好的处理了球心处的自然边界条件.通过计算并与解析法的结果比较,说明该差分格式正确,具有一般性.

Deduce difference scheme having arrived at sphere region Poisson equation and good have processed the natural boundary condition that the centre of sphere produces. Generality contrasting with analytical result,explaining that difference scheme correct,have by secretly scheming against.
