PASS/HYDROSYSTEM version 4.2 is released!

    PASS/HYDROSYSTEM version 4.2 includes the following improvements:
  • A new module of calculating slurry flow (mixtures of liquid and solid phases) has been added;

  • alculation of the unbalanced forces arising in a pipeline during waterhammer with their export to various pipeline stress analysis software, such as START-Prof and CEASAR II, has been added;

  • Reducer input has been simplified now the user only needs to specify their type (smooth or sudden) and the type of transition is automatically determined by the program;
  • Added the goal-seek analysis tuning now user can specify the maximum number of iterations and the allowable error of calculation;
  • Charts output to Excel (the results of waterhammer calculation, pipeline profile etc.) has been improved now the charts are displayed regardless of which separator of the integer and fractional parts is specified in Excel settings and Windows regional settings;
  • Fixed a bug leading to incorrect ground temperature for underground pipelines displayed in the input data report;
  • Fixed a bug in U-shaped expansion loops graphical presentation;
  • The calculation of the waterhammer wave velocity has been improved;
  • Fixed a bug due to which the waterhammer view-points could change their position when inserting a node;
  • Improved the data import from PCF files;
  • Some other minor bugs and typos have been fixed.
