FINITE DIFFERENCE METHODS FOR POISSON EQUATION
Dec 14, 2020 · The main drawback of the finite difference methods is the flexibility. Standard finite dif-ference methods requires more regularity of the solution (e.g. u2C2()) and the mesh (e.g. uniform grids). Difficulties also arise in imposing boundary conditions. 1. FINITE DIFFERENCE FORMULA In this section, for simplicity, we discuss the Poisson ...
