Getting that Stubborn AFT Fathom Model to Converge

The majority of steady-state, incompressible hydraulic models made in AFT Fathom that we see as Applications engineers typically converge very rapidly. However, every once in a while, that occasional AFT Fathom model arrives in our Support inbox that just won’t converge. At first glance, passing a graduate level course in compressible flow without ever missing an exam question may seem more likely than getting to the source of the convergence issue in one of these typically-monstrous models (like in Figure 1), but the tips below show that determining and correcting the problem preventing convergence is frequently straightforward and much easier than...
