Adaptive Mesh Refinement Using Wave-Propagation Algorithms for Hyperbolic Systems

摘要: An adaptive mesh refinement algorithm developed for the Euler equations of gas dynamics has been extended to employ high-resolution wave-propagation algorithms in a more general framework. This allows its use on variety new problems, including hyperbolic not conservation form, problems with source terms or capacity functions, and logically rectangular curvilinear grids. framework requires modified approach maintaining consistency at grid interfaces, which is described detail.
