Unsteady aerodynamic simulation of static and moving bodies using scalable computers

Methods to accurately .solve the Navier-Stokes equations for geometrically complex problems that may involve relative motion between configuration components are discussed. General curvilinear structured grids are used to discretize the volume of space in the near vicinity to configuration surfaces. Off-body domain volumes are discretized with uniform Cartesian structured grids of varying levels of refinement. Off-body grid refinement is automatically adapted in response to body movement and estimates of solution error. Near-body and off-body grid components are organized into groups of equal size. Method scalability is discussed. A set of three-dimensional applications are given to demonstrate method attributes on scalable computers and advantages for solving this class of problems.
