Modified flux-vector-based Green element method for problems in steady-state anisotropic media—Generalisation to triangular elements

This paper is concerned with the generalisation of a numerical technique for solving problems in steady-state anisotropic media, namely the ‘flux-vector-based’ Green element method ( GEM) for anisotropic media, to triangular elements. The generalisation of the method to triangular elements is based on the same concepts as for a rectangular grid, namely satisfying a nodal flux condition at each node of the mesh and the continuity of the tangential pressure gradient across the elements sharing a node.
