This paper describes the development and implementation of a three-dimensional Navier-Stokes code with explicit time integration on a massively data-parallel supercomputer, the Connection Machine (CM-200). The present algorithm employs first and second order interpolation schemes in space and explicit upwind differencing in time. Multistage stepping schemes are implemented to advance the time-marching part of the algorithm. The computational domain is discretized by dividing it into finite volumes. The resulting finite volumes are mapped in one-to-one fashion onto the CM-200 hypercube. The entire algorithm is implemented on the CM-200 using the C{sup *} programming language. Modest computational speedups are obtained over a similar code implemented on Cray-2.
