HPCMP CREATE™-AV Conservative Field Finite Element (COFFE) is envisioned as a numerical solver for partial differential equations designed to robustly solve a broad range of problems. To realize this goal, COFFE employs a modular software design that separates discretization, physics, parallelization, and linear algebra into distinct components. These components are developed with modern software engineering principles and are rigorously unit tested. Within COFFE, the Streamline Upwind/Petrov-Galerkin finte-element method is employed to discretize the compressible Reynolds-Averaged Navier-Stokes equations. This equation set is highly nonlinear, and an efficient and robust nonlinear solver is utilized to drive complex aerospace flow problems to a steady-state solution. The mathematics and philosophy of the methodology that makes up COFFE are presented as well as a variety of two dimensional test cases. These test cases include the calculation of the steady-state flow field surrounding a Joukowski airfoil under subsonic laminar and turbulent flow conditions, a NACA 0012 airfoil under transonic and supersonic turbulent flow conditions, and a 30P30N multi-element airfoil under subsonic turbulent flow conditions.
