3D FEM For Solving The Laplace Equation

There are many elegant analytical solutions to Laplace’s equation in special geometries but nowadays real problems are usually solved numerically. Computers and software are now so powerful that it can be easier to obtain a computer solution than to find the exact one in a reference book. Between two common approaches to finding a numerical solution finite difference and finite elements, we choose the second (FEM), since its powerful way to solve numerical problems.
