 A new overset grid assembly strategy for dynamic grid systemsHao Fu, Jian Xia and Shuling Tian Mathematics and Computers in Simulation (MATCOM), 2023, vol. 211, issue C, 171-191 Abstract: In overset grid assembly (OGA), the efficiency of assembly has been a major concern. In this paper, we propose an OGA strategy focuses on the re-assembly process in dynamic grid systems. Based on the recognition and expansion process of the hole boundary, we define a new set of cells for continuing OGA step. In this method, the number of cells participating in the new OGA process constitutes only a small portion of the primary grid system, leading to an acceleration in assembly and wall distance calculation. Not limited to the dynamic grid system, the static OGA is also improved based on the proposed method, without the need for additional mesh and only need minor changes to the program. We investigate cases including static and dynamic grid systems to verify the efficacy of the proposed method. The results confirm that the new method reduces the time consumption by 50% compared to the original method, particularly in the improvement of wall distance calculation.
