Cell centred discretisation of non linear elliptic problems on general multidimensional polyhedral grids
Robert Eymard 1, Thierry Gallouët 2, Raphaele Herbin 2
(2009)

This work is devoted to the discretisation of non linear elliptic problems on general polyhedral meshes in several space dimensions. The SUSHI scheme which was recently studied for anisotropic heterogeneous problems is applied in its full barycentric version, thus resulting into a cell centred scheme written under variational form, also known as 'SUCCES'. We prove the existence of the approximate solution and its convergence to the weak solution of the continuous solution as the mesh size tends to 0. Numerical examples are shown for the p-Laplacian.
