A numerical technique for simulating the dynamics and trajectory of multiple moving bodies is presented. A 6DOF model is fully integrated into the CFD solution procedure to determine the body dynamics. A highly automated Chimera technique has been developed and implemented into the software, CFD-FASTRAN, to achieve maximum flexibility and efficiency for CFD applications involving multiple moving bodies. The process is validated by application to a complex three dimensional store separation problem and compared against existing data. The code capability is further demonstrated by simulation of a missile tube launch.
