Description: A three-dimensional multi-block Newton-Krylov flow solver for the Euler equations has been developed for steady aerodynamic flows. The solution is computed through a Jacobian-free inexact-Newton method with an approximate-Newton method for startup. The linear system at each outer iteration is solved using a Generalized Minimal Residual (GMRES) Krylov subspace algorithm. An incomplete lower/upper (ILU) factored preconditioner with reverse Cuthill-Mckee reordering is utilized to increase the efficiency of GMRES.The parameters in the solver are optimized to provide a balance between speed and robustness. Tests are performed using a variety of flow conditions and grid sizes. Results are compared to experimental values and other established numerical solvers. The solver demonstrates fast convergence and accurate solutions on grids up to one million nodes.
