About this technology

Overview

GUNNS combines standard nodal circuit analysis algorithms with the hydraulic-thermal-electric analogy to allow modeling of flow circuits (fluid, thermal, electrical) with a concise set of generic code. Circuits are drawn up with a Draw.io drawing, from which run-time C++ code is auto-generated that can be built into sims. The GUNNS software includes custom Draw.io shapes for generic physical components like pumps, valves, resistors, & capacitors. These can be connected to each other in the drawing and configured with their characteristic values.
