Abstract
A coupling environment is presented which allows to couple two flow solvers with arbitrary spatial and temporal discretization. The design of the environment is described. The data exchange between the codes is based on Chimera interpolation techniques. The interpolation algorithms are generalized for interpolations close to curved surfaces in order to eliminate interpolation errors due to different surface discretizations. Flow simulations for a 2D NACA0012 airfoil and the aircraft configuration considered in the 4th AIAA Drag Prediction Workshopare are used to validate the method.
