Researchers at NASA’s Marshall Space Flight Center have patented software for analyzing steady state and transient flow in complex fluid networks. Originally developed to analyze propulsion systems, the Generalized Fluid System Simulation Program (GFSSP) version 5.0 is a general purpose, versatile flow modeling solution. The software incorporates thermodynamic property programs that draw upon an extensive library of fluid analyses, allowing users with a background in thermodynamics and fluid mechanics to model complex flow circuits quickly and easily. GFSSP version 5.0 also provides new capabilities for modeling fluid transient and conjugate heat transfer—including additional resistance options, fluids, and non-linear boundary conditions—through the application of user subroutines. With its flexibility and user-friendly graphical interface, this NASA Software of the Year Award winner is a unique predictive tool for multiple industries, achieving solutions for engineering problems not solvable via other means.
