Abstract
This paper describes a parallel strategy combing the Projection method and marker movement scheme to simulate free surface flow. The 2-D Navier-stokes equations were solved by using the two step Projection method while free surface location was tracked by putting massless markers on the surface. The main parallel approach is known as the Domain Decomposition. Stripe domain decomposition was applied for the parallel computation of momentum equation. A Schur domain decomposition scheme was used to parallelize the SOR algorithm for Pressure Poisson Equation. By analyzing the parallel computing procedure and the interprocessor communication cost, it can be found that the combination of the Projection method and Marker movement scheme has the potential to be an ideal structure for parallelism. The overhead cost for interprocessor communication is low leading to high efficiencies in the parallel computation.
