Abstract

A projection method for the correction of interpolation coefficients for overset grid CFD-simulations with grid overlap on body surfaces is presented. The concept of a virtual interpolation point ensures an interpolation with identical wall distance on grids with different surface discretizations. The algorithm can be applied for structured as well as for unstructured grids. Implementation issues and parallelization of the algorithm are discussed. Flow simulations for a 2D NACA0012 airfoil, a configuration considered in the 4th AIAA Drag Prediction Workshop and the DLR F11 high lift configuration are used to validate the method. The applications demonstrate the accurate interpolation of boundary layer data close to curved surfaces.
