Hopsan/hopsan v2.15.0

Release 2.15.0

on GitHub

Enhancements

• New C-API shared library wrapper for Hopsan core with Julia, Matlab and Python language wrapper, see:

  • Scripts/Julia/hopsan.j1
  • Scripts/Matlab/hopsan.m
  • Scripts/Python/hopsan.py

• Update to Qt 5.9.9 and MinGW-w64 5.4.0 on Windows
  If you are building component libraries externally from an IDE, make sure that you use the new compiler (included with Hopsan)

• HopsanCore:

  • Add Kinsol solver (libsundials) for solving algebraic equation systems
    This library source code is bundled with and compiled into HopsanCore

• HopsanCLI:

  • Enable HDF5 export of log variables from HopsanCLI
  • Improved parameter export, with the following changes since previous versions
    • Parameter export no longer prefix the subsystem name twice to system parameters
    • System parameters in the top-level systems are prepended with the reserved name "self"
      This means that old parameter files containing system parameters will no longer import correctly, without manual editing
      However, parameter import was broken anyway, so that should not be a big problem (fixed in this release)
  • Enable filtering --logonly results on individual variables in ports
    The entire port is still logged in memory, but only the desired variables are written to CSV file

• HopsanGUI:

  • The built-in python terminal has been removed, because it never worked well, and caused a lot of maintenance problems
  • Apply icon scale when adding subsystem components
  • Add automatic numbering and referencing of equations in markdown (LaTeX) help documentation.
    Use LABEL=name and EQREF{name} according to the example in:
    exampleComponentLib\HydraulicComponents\MyExampleOrifice.md
  • Display highest generation command in HCOM, adds "dihg" command and "hg()" function

• HopsanGenerator:

  • Use standard Modelica attributes for input and output variables in Modelica importer
  • Complete rewrite of Modelica generator and related functionality
    See the included ModelicaExampleLib

Bug Fixes

• HopsanCore:

  • Fix compilation issue and stack overflow when using MSVC compiler
  • Fix PLO v2 import bugs (import did not work)

• HopsanCLI:

  • Fixed broken parameter import
  • The command line argument --logonly, did not consider system ports on subsystems

• HopsanGUI:

  • Always reload models before starting a new optimization, this avoids running old models if you make changes between optimization runs
  • Correct tab names and tab indexes after restoring HopsanGUI state, when multiple models and/or text editors were opened
  • Fixed PLO v2 export bugs
  • Fixed markdown help not being shown when markdown file does not include equations
  • Fixed LaTeX rendering of parentheses and brackets in help equations, (Updated to KaTeX 0.12.0)

Component Libraries

• Add new component "AeroFlightRecorder" to the "AeroComponents" library
• Resolves problem in SignalLogger with exponentially increasing simulation time due to appending and reallocating data vector
• Fix SignalLogger file stream on Windows, so that all values get written
• Fix incorrect equations in Gas Accumulator (HydraulicAckumulator)
• Add missing embedded text support to PLOLookupTable
• Display components (for animation) now has parameters for description, unit, unit scaling, precision, background color and text color
