在2d possion equation中,给出了某个问题的初始条件和边界条件: p=0ateverywherep=0atx=0,2andy=0,1 源项为: bi,j=−100ati=nx∗3/4,j=3/4nybi,j=0everywhereelse 不用太在意这个例子有没有时间的物理意义,我们只需要在意一个possion方程,在四个边界上有边界条件,还附带了一个空间分布的源项,然后...
Since Poisson equation is based on the finite difference method (FDM), discretization is required for implementation. In 1D example, the discretization with grid size can be written as,(ϵn+1−ϵnΔ)(ϕn+1−ϕnΔ)+ϵnϕn+1−2ϕn+ϕn−1Δ2=−q(p−n+ND−NA...
