Abstract: A Modified Nodal Integral Method (MNIM) for three-dimensional, incompressible Navier-Stokes (N-S) equations has recently been developed. MNIM requires relatively less number of grid points for the desired accuracy. The Parallel MNIM (PMNIM) is developed in order to further enhance its capabilities. Since template of the nodal integral method is quite different from those that result from finite volume schemes, parallelisation of a nodal code has unique challenges. The PMNIM is applied to a test problem to evaluate its performance. It is observed that significant memory effects in the computations with variable problem size result in efficiencies greater than one.

Keywords: nodal integral method; parallel computation; 3D incompressible Navier-Stokes equations.
