Abstract : This Technical Memorandum presents an algorithm for deforming a two or threedimensional aerodynamic grid given deflections on a physical boundary. This algorithm is to be used in coupling a computational fluid dynamics code with a computational structural mechanics code. The deformation algorithm was tested successfully on both two and threedimensional grids. The method sufficiently maintalns grid quality for smooth deflections of realistic orders of magnitude. The method is computationally efficient: the time required to deform the grid is small compared to the time required to solve the fluid dynamics.
