A Non-Iterative Grid Deformation Algorithm for Computational Fluid Dynamics for Aeroelasticity.

Abstract

This Technical Memorandum presents an algorithm for deforming a two- or three-dimensional 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 three-dimensional 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.
