Abstract
AbstractA complete framework for solving the incompressible Navier–Stokes equations in parallel is presented. An unstructured mesh is decomposed into non‐overlapping subdomains corresponding to the number of processors. Each subdomain is adaptively refined independently based on local Reynolds number estimates. Computational load is balanced by transferring element‐octrees between subdomains.A parallel conjugate gradient solver with ILU preconditioning is achieved by resolving node dependencies based on mesh structure. Each node is sorted by category giving an a priori pivoting suited for parallel solution. The parallel solver has convergence rates comparable to serial solvers with a similar ILU strategy.
