How Does It Work?

AFT Fathom’s hydraulic solution engine uses the Newton-Raphson matrix iteration method plus proprietary methods developed by AFT to solve pipe flow and duct flow applications. AFT Fathom uses the Bernoulli Equation and Reynolds Number-based relationships for pipe friction calculation.
