EDGE. Navier-Stokes Solver for Unstructured Grids.

摘要

This report describes the compressible Navier-Stokes solver EDGE for unstructured grids. The solver is based on an edge-based formulation for arbitrary elements and uses a node-centered finite-volume technique to solve the governing equations. Two spatial discretizations of the convection terms are described, compact discretizations of the thin-layer and fully viscous terms have been proposed and evaluated. The governing equations are integrated explicitly towards steady state with Runge-Kutta time integration. The convergence is accelerated with agglomeration multigrid and implicit residual smoothing.
