An improved r‐factor algorithm for total variational diminishing (TVD) schemes on two‐dimension non‐uniform unstructured grids

For advection simulation, an improved r‐factor algorithm for total variational diminishing (TVD) schemes is proposed to extend the TVD schemes to non‐uniform unstructured grids. In the new algorithm, the further upwind node (called node U) location is modified based on the size differences of the re...
