ARC2D (Efficient Two-Dimensional Solution Methods For The Navier-Stokes Equations)(ARC-12112-1)

ARC2D is a computational fluid dynamics program developed at the NASA Ames Research Center specifically for two-dimensional airfoil and simply connected geometries. The program uses implicit finite-difference techniques to solve two-dimensional Euler equations and Navier-Stokes equations. It is based on the Beam and Warming implicit approximate factorization algorithm in generalized coordinates. The methods are either time accurate or accelerated non-time accurate steady state schemes. The evolution of the solution through time is physically realistic; good solution accuracy is dependent on mesh spacing and boundary conditions.
