Abstract
An unfactored implicit method for the unsteady, turbulent Navier-Stokes equations is implemented in parallel. The algorithm uses the alternating direction implicit (ADI) method as a preconditioner for a conjugate gradient solution of the linear system at each time step. The sequential nature of the ADI process is tackled by using a transposition method to solve complete ADI sweeps on single processors. Results are presented for a standard pitching aerofoil case solved on the iPSC
