How does it work?

AFT Arrow’s powerful solution engine simultaneously solves five fundamental equations; mass, momentum, energy, state and Mach number. It uses a modified Newton – Raphson matrix iteration method plus proprietary methods developed by AFT so you can achieve a true and rigorous compressible flow solution.
