## Aerodynamics and Path of a Paratrooper Separating from an AircraftThe core method used in these computations is the DSD/SST formulation [1-14, 17], which was developed by the T*AFSM for flow problems with moving boundaries and interfaces, including fluid-object interactions. The methods layered around include: mesh update based on automatic mesh moving with remeshing as needed; efficient projection of the solution after each remesh; and multi-platform computing. In earlier computations, simpler models of the aircraft and paratrooper were used [7-9]. Both models were improved for the computations reported here [15-16]. ## References: 1. T.E.
