Hello all! I am attempting to model the Laplacian of electric potential across a solid electrolyte, with an equation that is just the Laplacian of phi = 0. I have implemented this in two dimensions (4x2 rectangle), but I am struggling to create a 3D mesh that will accept the domain of a 4x2x2 box. …
