We define a finite differences method for triangular grids and we show how to link it to a finite element method. From this new point of view we then analyze properties of the solution and convergence.

The focus of this paper is on the solution of Maxwell's equations for time-harmonic "elds on triangular, possibly non-orthogonal meshes. The method described was "rst introduced in References 1 and 2 for eigenvalue problems arising in the design of accelerator components and dielectric loaded wavegu
## Abstract We present a family of centralβupwind schemes on general triangular grids for solving twoβdimensional systems of conservation laws. The new schemes enjoy the main advantages of the Godunovβtype central schemesβsimplicity, universality, and robustness and can be applied to problems with
