AN EFFICIENT CELL-BY-CELL ADAPTIVE MESH REFINEMENT ALGORITHM ON STRUCTURED GRIDS

Abstract

As an efficient AMR method on structured grids, a new cell-by-cell refinement algorithm is developed. Key idea of the new cell-by-cell refinement is to use categorized cell types which are originated from overset mesh technique. Thanks to categorized cell types, present method provides efficient cell-by-cell refinement algorithm, while preserving structured index of grid system. Through numerical test cases, the performance of present algorithm is investigated and comparison of accuracy and efficiency shows that present method is much more accurate and efficient than the case without AMR method.
