# COMPLEX SYSTEMS

## MAIN FEATURES

- Specification of fluid properties (density, specific weight, dynamic viscosity, compressibility)
- Representation of sewerage and drainage systems (branched configuration, looped configuration, branched and looped configuration)
- Definition of network topology through an unlimited number of nodes (inlet, outlet, manhole, junction, etc.) and links (pipe, valve, pump, overflow weir, 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
- 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
