Simulation of a Torpedo Launch Using A 3-D Incompressible Finite Element Solver and Adaptive Remeshing.

Abstract

An implicit finite element solver for three dimensional incompressible flows with adaptive remeshing has been developed. This flow solver is employed for the simulation of an unsteady torpedo launch from a submarine. Several mesh movement algorithms have been developed and implemented. The use of gliding points on surfaces in the vicinity of a moving body has proven valuable in reducing the number of remeshings and thus reducing the total CPU time required for the simulation. The adaptive flow solver has been parallelized and is written in a manner that allows portability among various supercomputer architectures. (AN)
