Several fluid-dynamics codes have been ported to the Intel iPSC/2. In particular, Nekton* is a package for modelling the incompressible Navier-Stokes equations. Nekton is based on spectral elements and incorporates a conjugate-gradient solver. The elements are distributed over the nodes of the iPSC/2 and the solver uses a microcoded matrix-matrix product on each node to obtain performance of 10 MFlops per node. Passage* is a package for modelling the steady Navier-Stokes equations for internal flows such as ducts and turbines. It uses a block-structured finite-difference approach to domain decomposition which lends itself naturally to parallel implementation. FLO87* is a compressible Navier-Stokes code using finite-volume multigrid methods for fast convergence on steady flows. Its logically cubical computational domain is divided into blocks to be distributed over the iPSC. Each of these codes has a straight-forward parallel decomposition because of the regularity of its data structures and dependencies.
