Abstract

A new approach to block-structured adaptive mesh refinement is developed based on summationby-parts (SBP) operators and simultaneous-approximation-term (SAT) methodologies. Relative to typical block-structured AMR where grid boundaries match, the new approach allows the meshes to overlap and is energy stable. Schemes are developed separately for the advection and diffusion equations before addressing the advection-diffusion equation. Theoretical predictions are confirmed by numerical experiment.
