Steady State Network Calculation

The dialog "Steady State Network Calculation" serves to input, modify, and start steady-state network calculations. The regulations and the distribution of load for calculation are set in this dialog, as well the configuration of the design defaults.
  • Calculation – Give your network calculation a name here.
  • Start network calculation – Implements the network calculation with the settings made. If calculation is terminated with messages, sisHYD automatically opens the error log. After successful calculation (without fatal error) the calculation results are imported and can be evaluated in the report center.
    • The progress display of the calculation is displayed only if calculation time amounts to multi than one second. It serves to cancel the calculation being carried out in the background if necessary. The display closes automatically when the calculation finishes.
  • Close – Closes the progress bar after successful calculation.
  • Cancel – Cancels current calculation.
  • Give your network calculation a name here.
  • Start validation – Carries out an examination of the network data and calculation specifications. The validation uncovers potential errors, which are recognizable before a calculation. Detected defects are written in the calculation log and the log is opened if the validation fails.
  • Display log file – Displays the log with messages about network calculation. Is if the symbol is greyed out, no log is available for the calculation.
    • The log is written in HTML format and displayed with the default Internet browser. There are hyperlinks behind highlighted object names in the messages, which open the corresponding data records in sisHYD. See sisHYD browser.
  • Start design wizard – Starts the assistant for the adopting of design results (i.e., the adoption of determined pipe classes according to the design criteria). The switch is active only if a valid design calculation has been carried out.
  • Open report center – Starts the report center for the evaluation of the calculation results. The evaluation covers a summary of the calculation as well as numerous reports for the different installation components and regulations. With the reports there are also many min & max evaluations with an adjustable number of data sets sorted according to the evaluation criterion.
    • The report center displays a tree view of the possible evaluations in the left window area. The min/max reports themselves sort the elements in ascending order of the evaluation criterion (separately for each network position).

✍ The displayed reports depend on the category, the medium as well as the existing installation components; if no valves are present in the current project, for example, then no reports for valves are offered.

The listed designated objects have hyperlinks that open the corresponding object in sisHYD when clicked. See sisHYD browser.
