The solver uses Newton–Raphson for looped networks and checks mass balance at every junction.

Field notes

The workflow starts with a flowsheet: users join segments at nodes and list each segment's pipe, valves, and fittings in flow order. After selecting a fluid and setting boundary conditions, results appear by segment and node, with CSV export available. The page lists 50 fluids plus steam and says cases stay on the user's computer. Non-Newtonian liquids, slurries, and two-phase flow are explicitly marked as planned rather than available.
