Networks engine

Built on it

• Fire sprinklers — Layout and hydraulic calculation.
• HVAC — Ducts, fittings, equipment, sizing.
• Hydraulics and surge — Steady flow and water hammer on piping.
• Oil and gas (upstream, pipelines) — Pipeline sheets for CivilCraft, CadCraft and BimCraft: gas and liquid pipeline wall thickness, gas line pressure drop, liquid pump spacing and hydrostatic test.
• Piping — Pipes, fittings, specs, isometrics.
• Piping and plant design — Piping sheets for CadCraft and BimCraft: line size from velocity, line pressure drop, pressure-design wall, thermal expansion and pump power.
• Power systems — Load flow, short circuit, coordination.
• Power systems and utility engineering — Power sheets for CivilCraft and CadCraft: conductor sag and tension, transformer fault current, three-phase voltage drop and power factor correction.
• Renewable energy (solar, wind, storage) — Renewable-energy sheets for CivilCraft, BimCraft and CadCraft: wind power, Jensen wake, PV yield, PV string length and battery storage sizing.
• Solar PV — Arrays, shading, yield, strings, one-line.
• Telecommunications and fiber networks — Telecom, survey and network items for CivilCraft and CadCraft, with three calculation sheets: fiber loss budget, radio horizon with Fresnel clearance, and duct fill.
• Wastewater and water treatment — Wastewater and network tools for CivilCraft and BimCraft with four sizing sheets: activated-sludge tank, oxygen demand, clarifier and contact tank.
• Water networks — Water, sewer and storm networks.

Use it in your add-on

Name it in your manifest's needs. When someone adds your add-on, their account brings this engine too, and every edition loads it the first time your add-on needs it. Version ranges arrive with AL.13.

Methods and standards

The tests name the methods: a gradient solver for pipe networks checked against Hardy Cross, Newton-Raphson load flow checked against Gauss-Seidel, and closed forms and published constants for short circuit and protection curves.

Limits

Lab. A calculation aid: an engineer checks every result. Not yet verified against benchmark networks. The older mep/network code in BimCraft is partial and is to be brought onto this engine.
