ulate a discrete variational principle for the potential energy .. This is accomplished by writing down a second-order accurate discrete approximation of . based on a rectangular mesh. To arrive at finite difference equations for equilibrium, we set the derivatives of the approximation of . with res

ite simple and only requires following the instructions presented in this chapter. However, an understanding of the theoretical framework is needed to determine the scope and limitations of the method, to choose the most efficient parameters, and to interpret the results correctly.
