Hopsan/hopsan v2.17.0

Release 2.17.0

on GitHub

Enhancements

• BuildSystem:

  • CMake build system can now build all Hopsan parts and support for the Microsoft Visual C++ compiler has been added
    Some issues still remain for CMake / MSVC builds, so this is not yet the default build system
    Build instructions have been updated, if you wish to use this build method

• Documentation:

  • Add link to tutorials under the help menu in HopsanGUI. There is now a more in-depth tutorial on the TLM method available.

• HopsanC:

  • List alternatives when querying for illegal port or variable names

• HopsanCore:

  • New "quantity" LeakageCoefficient added with various scale factors
  • Add Component::reconfigure() function that components can overload to reconfigure themselves
    Reconfigure is triggered when a parameter registered with the Component::setReconfigurationParameter(const HString &rName) function
    is changed.

• HopsanGUI:

  • Do not trigger auto complete popup after @
  • Do not auto select auto complete item while typing, user must press Tab, arrow keys or select with mouse
    This avoids the very annoying unintentional auto complete
  • Auto complete now replaces the entire completer prefix, to ensure that case is corrected
    Example: step.out.y -> Step.out.y
  • Fix auto complete not recognizing . in names such as Step.out.y
  • If you invert a plot curve using the curve controls, the setting will be remembered for the next generation
    If you want the invert curve setting to be persistent, check the box in the component properties instead
  • HCOM "edit" command now opens supported files in the Hopsan text editor instead of external editor (which quite often is not found)

• Ops

  • Add elites parameter in genetic algorithm
    The best individuals are always carried over to the next generation without crossover and mutation.
    This helps avoid degradation of solution quality between generations.

Bug Fixes

• HopsanC:

  • Header file for hopsanc was not included in release

• HopsanGUI:

  • Do not clear undo-stack when a connector can not be found
  • Prevent renaming subsystem copy twice
    Fixes invalid name lookup for attached connector in undo
  • Fix hand icon getting stuck (finally after all these years)
  • Fix pasting system ports with connections
    They are no longer lost due to port being renamed
  • Fix enable/disable undo action syncing with changes in systems
  • Fix redo for subsystem paste
  • Process undo items in reverse order
    So that sub-operations are undone in the correct order
  • Fix redo for text widgets
  • Fix model lock-level detection for top-level system
    Prevents changes to model when model is locked
  • Prevent paste while left mouse button is pressed
    It would mess with the positions of the pasted components
  • Maybe fixed crash when simulation is finished, related to progress bar handling
    The problem could not be reproduced reliably (by the developers) so hard to know if it is fixed
  • Remove fade effect on red error flash in terminal, on some systems it would take a long time to fade
    Replaced by 400 ms solid read background
  • Fixed lock axis setting was forgotten when browsing to an empty generation
  • Fix splash screen not including version number and mentioning "development version"

• Ops:

  • Check for minimum number of candidates in DE algorithm, to avoid crash.
    DE algorithm requires four points

Component Libraries

• Renamed ContainerPort to SystemPort
  Containers (a type of system) were removed from Hopsan several years ago
• Turn off rotation for various signal component icons with symbols
• Added missing unit to leakage parameter for all pump/motor components
  Set the same default value for leakage parameter to 1e-12 for all pump/motor components
• Use consistent default parameter value for density 870 kg/m^3 in the default component library
• New component: Hydraulic differential pressure sensor
• Obsolete CppComponent and ModelicaComponent traces removed (were causing warning messages)
  The HopsanGenerator can generate proper components, so the old wrappers are no longer needed (and they no longer work)
• New component: (Extension library) Experimental FMI wrapper using reconfigure rather then requiring recompilation
