On stability and accuracy of finite-volume schemes on non-uniform meshes

P. A. Bakhvalov, M. D. Surnachev


Abstract: The paper studies the behavior of high-order finite-volume schemes for the 1D transport equation on non-uniform meshes. We consider finite-volume schemes with a polynomial reconstruction and schemes based on divided differences. We prove a sufficient stability condition on mildly deformed meshes and establish estimates for the solution error.

Keywords: finite volume method, consistency and accuracy, supra-convergence, long­time simulation accuracy.
