There are 16 atoms. I get a row matrix of charge density(rho) from negf solver of size 1×16. x axis is the transport direction with bias voltage 0.5V. in z axis I apply electric field of 5V. In y axis electrostatic doesn’t change. I want dirichlet boundary condition in x axis. Neumann boundary in z axis. Periodic in y axis. All atoms with lowest & highest x values correspond to boundary in x direction. And atoms with lowest & highest z values correspond to boundary in z direction. Poisson equation to be solve is in form Del^2U(x,y,z)=-rho(x,y,z)/epsilon. Any guide on how to do it using solvepde?These are coordinates of atoms:
