Are there any softwares that can solve Poisson equation numerically
directly,matlab, mathematica or others?
I mean that it will give you the result without writing code by yourself?

Thanks.
Are there any simple Poisson equations that have the analytical solution?
I just download some programs to solve Poisson equations.
But I have no data to verify that the program is correct.

你可以自己弄一个
比如区域为[0,1]*[0,1],边界上值为0
然后你去u=x(1-x)y(1-y)
计算一下f
即可
