Abstract

The author reports on work devising massively parallel implementations of vortex methods for computing turbulent flow in highly complex geometries. The challenges involved in fitting evolving compilers, hardware, and I/O to nontraditional fluid mechanics techniques, N-body solvers, and interactive real-time visualization environments are discussed. The results describe algorithms to compute two and three-dimensional inside chambers and around bluff bodies. Some issues involved in developing intuition about parallel implementation of complex codes are examined.
