    Graduate Numerical solution of the Poisson equation

    Thank you for your response! Suppose that ##\rho(x')\approx const## in ##|x' - x| < \delta x.## Redefine the variable ##x' - x = \xi.## Wouldn't the error in a one-dimensional Cartesian system then be the same as below: $$\delta\varphi \propto \int_{-\delta x}^{\delta x} \frac{d\xi}{|\xi|} = 2...

    Graduate Numerical solution of the Poisson equation

    In my case, there is proton radiation acting on the material. Consequently, the protons get stuck in the sample and create an electrostatic field. I would like to solve the Poisson equation inside the sample. I assume that the medium is infinite and homogeneous, that is, the potential at...
