Finite Difference Grids

This lecture covers the concept of finite difference grids, focusing on the computation of solutions for elastic membranes using Laplace's equation. The instructor explains the process step by step, from defining the problem to applying finite difference formulas and boundary conditions. Various numerical methods are discussed, such as stencil patterns and the goal of computing approximations. The lecture emphasizes the importance of accurately representing the problem on a discrete grid for efficient computation.
