AFT Arrow is a highly accurate and powerful compressible flow analysis tool and rather than solving various compressible flow correlations, AFT Arrow is simultaneously solving the fundamental mass, momentum, energy, Equation of State, and Mach number equations.  Although AFT Arrow accurately calculates the fluid physical properties throughout the compressible pipe network, there is also a high level of complexity associated with these calculations. We have seen several models that have various convergence issues and there is a common troubleshooting technique that solves the majority of these issues.  This technique is simply changing the specific heat ratio accuracy option from “High” to...
