abstract = {<p style="text-align: justify;">A nonlinear finite volume element scheme for anisotropic diffusion problems on general triangular meshes is proposed. Starting with a standard linear conforming finite volume element approximation, a corrective term with respect to the
flux jumps across element boundaries is added to make the scheme satisfy the discrete maximum principle. The new scheme is free of the anisotropic non-obtuse angle
condition which is a severe restriction on the grids for problems with anisotropic diffusion. Moreover, this manipulation can nearly keep the same accuracy as the original
scheme. We prove the existence of the numerical solution for this nonlinear scheme
theoretically. Numerical results and a grid convergence study are presented for both
continuous and discontinuous anisotropic diffusion problems.</p>},
