This paper reports the development of a solutionadaptive technique using unstructured hexahedral meshes for unsteady compressible flow simulation. A simple data structure that uses only two topological entities, cell and face, is proposed to avoid data dependency that is encountered when implementing unstructured data for vector and parallel processing. Two flow solvers are constructed based on two different schemes. One scheme belongs to the MUSCL family, while another employs a second-order central-difference scheme with artificial viscosity. The parallel performance on three supercomputers is reported. A numerical example of unsteady shock motion from a square tube to a circular tube is demonstrated.
