A global method of generalized differential quadrature is applied to solve the two-dimensional incompressible Navier-Stokes equations in the vorticity-stream-function formulation. Numerical results for the flow past a circular cylinder were obtained using just a few grid points. A good agreement is

The potential for using a network of workstations for solving the incompressible Navier-Stokes equations using a finite element formulation is investigated. A programming paradigm suitable for a heterogeneous distributed workstation cnvironrnent is developed and compared to the traditional paradigm
## Abstract This article mainly concerns modeling the stochastic input and its propagation in incompressible NavierβStokes(NβS) flow simulations. The stochastic input is represented spectrally by employing orthogonal polynomial functionals from the Askey scheme as trial basis to represent the rando
