The objective of this proposal is to demonstrate a new method that will make possible the treatment of large-scale problems with current computational resources. The idea behind the proposed technique is the use of analytical rotated overset grids to define the geometry. Instead of exactly fitting the bodies, an immersed boundary technique will be used, allowing the use of cylindrical, Cartesian, spherical, elliptic or other analytical orthogonal grids to cover the whole computational domain. Since the geometry of these grid topologies have explicit analytical equations, the donor search and optimization algorithms needed for the overset domain connectivity become extremely efficient. The proposed approach then can combine highly scalable algorithms for the solution of the CFD problem in orthogonal grids along with the advantages of overset grids. Phase II of this proposal will result in a highly scalable and accurate CFD code for moving/deformable objects such as a towed array and the towing vehicle.
