Abstract

This paper presents a new technique to parallelize Newton method for the locally conical approximate, laminar Navier-Stokes solutions on a distributed memory parallel computer. The method uses Newton's method for nonlinear systems of equations to find steady-state solutions. The parallelization is based on a parallel iterative solver for large sparse non-symmetric linear system. The method of distributed storage of the matrix data results in the corresponding geometric domain decomposition. The large sparse Jacobian matrix is then generated distributively in each subdomain. Since the numerical algorithms on the global domain are unchanged, the convergence and the accuracy of the original sequential scheme are maintained, and no inner boundary condition is needed.
