Abstract: We construct a monotone continuous Q 1 finite element method on the uniform mesh for the anisotropic diffusion problem with a diagonally dominant diffusion coefficient matrix.The monotonicity implies the discrete maximum principle.Convergence of the new scheme is rigorously proven.On quadrilateral meshes, the matrix coefficient conditions translate into specific mesh constraints.
