FINITE DIFFERENCE METHODS FOR POISSON EQUATION
FINITE DIFFERENCE METHODS FOR POISSON EQUATIONLONG CHENThe best well known method, FINITE differences , consists of replacing each derivativeby a DIFFERENCE quotient in the classic formulation. It is simple to code and economic tocompute. In some sense, a FINITE DIFFERENCE formulation offers a more direct and intuitiveapproach to the numerical solution of partial differential equations than other main drawback of the FINITE DIFFERENCE METHODS is the flexibility. Standard FINITE dif-ference METHODS requires more regularity of the solution ( C2( )) and the mesh( uniform grids). Difficulties also arise in imposing boundary FINITE DIFFERENCE FORMULAIn this section, for simplicity, we discuss the POISSON EQUATION u=fposed on the unit square = (0,1) (0,1)with Dirichlet or Neumann boundary condi-tions.
