# COMPLEX SYSTEMS

## MAIN FEATURES

• Specification of fluid properties (density, specific weight, dynamic viscosity, compressibility)
• Representation of transport and distribution systems (branched configuration, looped configuration, branched and looped configuration)
• Definition of network topology through an unlimited number of nodes (reservoir, storage tank, surge tank, junction, etc.) and links (pipe, valve, pump, turbine, etc.)
• Definition of characteristics for each node (3D coordinates, geometry, constraints, initial conditions, working conditions, etc.)
• Definition of characteristics for each link (geometry, friction losses, characteristic curves, operational laws, control laws, etc.)
• Solution of algebraic and differential equations through the MOC method and an iterative procedure
• Choice between DDA (Demand Driven Analysis) and PDA (Pressure Driven Analysis)
• Computation of flows (velocities, volume flow rates)
• Computation of heads (gravity, pressure, energy)
• Computation of convergence tests (mass balance, number of iterations)
• Analysis of steady state conditions
• Analysis of unsteady state conditions
• Comparison of results with available field data
• Visualisation of results
• Suitable for designing and testing
