A symmetric finite volume scheme for selfadjoint elliptic problems. (English) Zbl 1027.65150
The authors introduce a new symmetric finite volume scheme for a general self-adjoint elliptic boundary value problem. Some relations between finite volume methods and finite difference methods are discussed. Some error estimates are provided for the $$L^2$$-norm, $$H^1$$-norm and $$L^{\infty}$$-norm. Furthermore, post-processing techniques are presented. Finally, some numerical results are performed on two academic cases.
