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
