Abstract

Purpose

The purpose of this paper is to propose a parallel partition of unity method (PPUM) to solve the nonstationary Navier-Stokes equations.

Design/methodology/approach

This paper opted for the nonstationary Navier-Stokes equations by using the finite element method and the partition of unity method.

Findings

This paper provides one efficient parallel algorithm which reaches the same accuracy as the standard Galerkin method but saves a lot of computational time.

Originality/value

In this paper, a PPUM is proposed for nonstationary Navier-Stokes. At each time step, the authors only need to solve a series of independent local sub-problems in parallel instead of one global problem.
