Why Block-Structured AMR?

Block-structured AMR provides a way to exploit varying resolution requirements in space and time by focusing computational resources in spatiotemporal regions of interest. Note that there is no parent-child relationship between coarser grids and finer grids as the grid structure dynamically evolves over time.

Depicted above is the development of a cold dodecane jet into a hot chamber using 3 levels of refinement demonstrating solution-adaptive mesh refinement.
