The works listed below document the methods implemented in GLN Analysis: the Darcy-Weisbach formulation of distributed losses and the friction-factor correlations used to close it, the loss-coefficient treatment of fittings, the thermo-physical correlations of the antifreeze solutions, the reference cases against which the solver is verified, and the design practice the panel's advisory checks are drawn from.
