抄録

This paper describes a simulation of octree with AMR using Fully Threaded Tree with Pedigree (pFTT) data structure that is most suitable for adaptive mesh strategy amongst standard, FTT and pFTT data structure. To validate the present approach, a simulation of the flow around a heated cylinder was performed on pFTT using AMR with temperature gradient as an index for refinement and un-refinement of cells. In the cylinder wake the finest cells were generated and moved along with the advection of Karman vortices.
