Nonelliptic Approximation of a Class of Partial Differential Equations with Neumann Boundary Condition
Nonelliptic Approximation of a Class of Partial Differential Equations with Neumann Boundary Condition
This paper is devoted to the numerical resolution of a class of linear partial differential equations with an inhomogeneous Neumann boundary condition. A first order quadrilateral finite element method is used, together with a one-point integration formula. The resulting scheme is simple and widely used but its theory is not …
