In this paper, we present an ultra-high-speed adaptive meshing using a hierarchical method, which has been often used in the computer graphics field. If the hierarchical mesh is used, meshes can be changed very quickly. We have applied this meshing successfully to the adaptive analysis of 3D cavity flow, interpolating the values (flow velocity, pressure or error) at the nodes after re-meshing from those before re-meshing without reconstruction of the hierarchical data structure.
