Stationary Partial Differential Equations independent variables: space coordinates boundary value problems no start and end

Discretization space grid functions operators large system of linear equations typically sparse finite difference/volume/element

Iterative Solution of Systems of Linear Equations point-by-point processing eliminate local residual iterate Gauss-Seidel solver exploit sparsity
