WebAbstract This paper describes data structures and algorithms for the automatic generation of adaptive subgrids, a technique used with adaptive mesh refinement for solving partial differential equations. Our algorithms generate a nested sequence of finer and finer grids on an underlying coarse grid. There are two aspects to the data structures. Web1. Multiple circles stacked together form a curved surface. 2. Any point on a curved surface is equidistant from its centre and this distance is called the radius. 3. A flat surface can be rolled to form a curved surface, and if …
