Abstract: A parallel CFD-algorithm on adaptive mixed meshes with elements of the tetrahedron, prism, pyramid, and hexahedron type is presented. The algorithm is based on a explicit high-order accurate finite-volume method for Navier-Stokes equations with polynomial reconstruction of variables. The distributed algorithm for heterogeneous supercomputers is developed using the MPI, OpenMP and CUDA software models. Numerical results for supersonic flows and the parameters of the software efficiency are given.

Keywords: computational fluid dynamics, unstructured mixed mesh, adaptive mesh refinement, parallel computing.
