Adaptive mesh generation for viscous flows using Delaunay triangulation
Dimitri J. Mavriplis · NASA Technical Reports Server (NASA) · 1988
A method for generating an unstructured triangular mesh in two dimensions, suitable for com-puting high Reynolds number flows over arbitrary configurations is presented. The method is based on a Delaunay triangulation, which is performed in a locally stretched space, in order to obtain very high aspect ratio triangles in the boundary layer and wake regions. It is shown how the method can be coupled with an unstructured Navier-Stokes solver to produce a solution adaptive mesh generation procedure for viscous flows.
