Abstract

For CFD simulations on overset grids with grid overlap on body surfaces the Chimera interpolation scheme must be extended to allow for an accurate interpolation inside boundary layers. For this purpose a projection algorithm is introduced which ensures an interpolation with identical wall distance on grids with different surface discretizations. In order to compute loads like lift and drag an algorithm is presented which removes the grid overlap and fills the gap with a triangular mesh. The methods are successfully implemented into DLR’s unstructured flow solver TAU and are applied to a flow simulation for a wing-body airplane configuration.
