Structured grid vs unstructured grid
WebA simpler case of a structured grid pattern is solving problems mapped to 1, 2 or 3 dimensional grids. Each processor is assigned a chunk of the grid that is statically or dynamically determined by a partitioning algorithm. Each processor then computes the updates of the grid points in its chunk of data in each iteration. “Ghost” nodes WebSep 19, 2024 · Compared with the hexahedral corner point grid (CPG), GPG is a polygon prism and therefore more flexible; whereas, compared with the 2.5D perpendicular bisection (PEBI) grid, GPG allows polygons morphing through the stratum. We built a gridding algorithm to fulfil the features of GPG.
