I beleive that fipy can solve my simple problem. But I spend many time to figure it out , but I can not. I need your suggestions, or maybe can not solve in fipy.
Poisson's equation $-\nabla\cdot\nabla p = q1 + q2$ admits an infinite number of solutions. You obtain a particular solution by specifying a boundary condition. This is not unique to FiPy. If you "ground" p by giving it a FixedValue boundary condition, then your code produces stable solutions.
