Title:
Adaptive mesh refinement and sub-cell discontinuity resolution for high order DG discretizations
Abstract:
The development of a unified efficient approach for discontinuity capturing with higher- order (P2 or higher) DG discretizations in three-dimensional unstructured meshes is presented. To retail high order accuracy both at discontinuities (with sub-cell discontinuity resolution) and away from them in order to resolve smooth but complex flow features application of p-type adaptivity is proposed. To advance in time the full coupled system for chemically reactive flows, electromagnetics with added potential flow fields to retain the Gauss constraints for the magnetic and electric field and other stiff problems but also high very high order DG discretizations implicit time marching is applied. Using these elements dynamic h/p refinement for time dependent complex three-dimensional flow problems is presented.
