AMRFLEX3D — Flow Simulation Using a Three-Dimensional Self-Adaptive, Structured Multi-Block Grid System

  • R. Hentschel
  • E. H. Hirschel
Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NONUFM, volume 48)


The first section gives a description of the numerical procedure which is used for the integration of structured grid blocks. Such blocks are the basic elements of the self-adaptive grid structure. A hierarchically ordered level system, which reflects different refinement stages, serves as a scaffold. After a description of sensors used for refining interesting flow phenomena, an overview about the integration steps is given. The application of AMRFLEX3D to the cases of a three-dimensional, inviscid, supersonic corner flow and of a delta wing at transonic flow conditions is presented. For the latter simulation, both Euler and Navier-Stokes equations are used. Conclusions that can be drawn from experiences with grid refinement investigations are given.
