摘要: Vertex-centroid schemes are cell-centered finite volume for conservation laws which make use of both centroid and vertex values to construct high-resolution schemes. The must be obtained through a consistent averaging (interpolation) procedure while the updated by scheme. A modified interpolation scheme is proposed better than existing in giving positive weights formula. simplified reconstruction also more efficient leads robust discontinuous problems. For scalar laws, we develop limited versions stable maximum norm constructing suitable limiters. applied compressible flows governed Euler equations inviscid gas dynamics.
