STANET® Features

General

The following list includes requirements on program systems used for simulation of fluid mediums (gas, water, district heating, steam, oil, compressed air, sewage), which STANET® will provide.

Integrated Database

The graphic coordinates are saved together with the objects (nodes, pipes, etc.) in a common database leading to a consistent data model.

Extended Database Functions

  • Filter to create defined subsets (e.g. select pipes with diameter between 100 and 400 mm)
  • Output of free configurable lists on display, printer or file
  • Using of numerical operations, e. g. average, maximum, minimum and sum on selected values (pipe length, pipe diameter, etc.)
  • Substitute any value as result of other (e. g. pressure height = elevation + pressure * 10.2)
  • Search for values (node name, velocity, etc.)
  • Deleting objects
  • Sort by value
  • Classify, e.g. number of pipes to any existing diameter
  • Creating user defined objects or attributes (fields)
  • Automated back documentation of actual used attribut definitions

Extended Calculation Functions

  • Proof of the topology (number of subnetworks, insertion errors)
  • Models of valves, pipe valves, pumps, reservoirs, consumers, regulators, service pipes, etc.
  • Mixture of any medium contents (heating value, nitrate concentration)
  • Calculation of temperature loss along pipes
  • Automated simulation of hierarchical networks (high pressure, intermediate pressure, medium pressure, low pressure)
  • Consideration of coincidence factor (different to time and consumer groups)
  • Interpolation of height values from elevation benchmarks
  • Calculation of consumer distributions from the commercial statement of consumption
  • Free configurable boundary conditions: several pressure nodes and unknown inflows/outflows
  • Using elimination instead of the Hardy-Cross-Method to improve numerical exactness and simulation time, only growing linear depending on the number of nodes (needs 2 seconds for 10,000 nodes on Pentium II 300 MHz)
  • Calculating pump characteristics from measured values
  • Determine internal diameter from a pipe type table administrated separately
  • Simulation of consumptions depending on given outside temperature
  • Optional simulation of service pipes
  • Saving different simulation cases of one network
  • Dynamical simulation of successive loads with storage in reservoirs/pipes and showing results in time diagrams.
  • Automated calculation of water for extinction

Graphic Functions

  • Zoom in, zoom out, moving views
  • colored network elements, each color representing a numeric variable range (i.e. all nodes with low pressure in red color)
  • pipe representation with different line width depending on the diameter
  • pipe representation with different line types
  • two different network representations: switch between schematic and real world coordinates
  • selective representation of network element groups (layer technology)
  • input via keyboard, mouse or digitizer
  • inserting text or polygon lines with any size or color
  • display technical data on nodes and pipes in the network map
  • control valves and pumps via mouse
  • automatic decluttering: details are displayed depending on the zoom factor and the available space
  • mapsize independent output of maps onto printer or plotter
  • free configuration of textsize, independent for element classes and for monitor/plotter
  • preview for plotter/printer
  • optional display of cataster lines
  • optional display of raster points for insertion
  • selection of objects laying one upon another
  • selecting several object by mouse click, with lasso or rectangle function
  • selected objects may be deleted, copied and inserted on another place or into another network
  • displaying background pictures: pixel format (more than 36 formats, e. g. TIFF, BMP etc.) and AutoCad-12 vector format
  • displaying background pictures depending on scale, supported by a fast memory manager
  • using text font with any color or font face for technical data and free text
  • creating spatial profile diagrams
  • calculation of area size
  • Output of networks with printer, plotter or into file using HPGL or AutoCAD-DXF
  • Measurement for objects

Connectivity

  • data should be imported and exported with standard file formats (ASCII text, ODBC, dBase, Windows-Clipboard)
  • user defined objects and fields
  • running in a network (Novell, NT)
  • free configurable import and export interface for column orientated text files
  • taking over data from external annual statement of consumption programs
  • Import/Export of network data:
    • ArcView
    • GANESI (Technical University of Munich)
    • GEOGRAT / GEOGIS
    • MapInfo
    • ODBC
    • Smallworld
  • GIS/CAD interfaces for import of network data:
    • AutoCAD
    • AutoGIS
    • GARONE/WARONE
    • Gradis 2000 (Straessle)
    • IBM-GTIS: GPG
    • Magellan (Geoinform)
    • Moskito
    • PARIS (Hemminger)
    • Optiplan
    • Pegasus
    • ROKA
    • SICAD-SQD (Siemens)
    • SINCAL
  • integration into GIS systems in batch mode (start calculation from another system)
  • STANET is portable onto different systems
