Part of the Notes on Numerical Fluid Mechanics (NNFM) book series (NNFM, volume 44)

Summary

Numerical solutions which simulate compressible flows can be greatly improved by mesh adaption. This paper describes the grid adaptivity techniques for mesh refinement, mesh derefinement and node movement. To achieve this flexibility the adaption must be implemented using a suitable data structure, details of which are given. For application to complicated geometries structured, unstructured and hybrid grids are used. Aspects of these mesh generation techniques will be described. Mesh adaptivity will be demonstrated on a variety of 2-dimensional aerospace applications for both inviscid and viscous flow simulation.
