Release Notes DSHplus

DSHplus Release 3.14

Bug fixes

  • DSHplus 3.14 is a pure bugfix release that fixes some errors in the component library.

DSHplus Release 3.13

Changes

  • Models exported as FMU are now executable on all platforms without DSHplus licence
  • Nested FMUs are now more addressable and can be used directly in conjunction with the VEL Real-time System
  • The numerical stability of the models was increased
  • The library "Pipes with distributed parameters" is depercated. It will be replaced in the next release by the new "Piping Systems" library, which is currently available on request.
  • New component: Variable Hydrostatic Unit

Bug fixes

  • When saving results, the programme could crash in some cases
  • Fixed a bug where parallel installation of the regular and Altair versions of DSHplus could cause problems
  • Models with submodels may not have been created correctly
  • The logging of FMUs calculated in parallel could cause the programme to freeze
  • Timing and error handling in FMU component corrected

DSHplus Release 3.12

Changes

  • Import of Functional Mock-up Units (FMU) according to FMI 2.0
  • All binary files are digitally signed
  • The DSHcalc export can export multiple parameter sets for external batch processing
  • The DSHcalc export optionally packs all export files into a tar.gz file
  • Parallelization of models with adapted components (e.g. FMU)
  • Editable parameters of DSHplus-FMU
  • Upgrade of the model compiler (MinGW v7 with GCC 9.2)

Bug fixes

  • Formulas in variables were ignored when importing parameter sets
  • Already exported FMUs could possibly not be overwritten
  • In the formula interpreter a division by zero could lead to a program crash
  • Timeout error in the Co-Simulation Tool
  • Opening projects could cause a crash if a model was already loaded
  • Parameter changes with very small values were not saved in some cases
  • Fixed a bug in the report function that could cause DSHplus to crash

DSHplus Release 3.11

Changes

  • Model compiler upgrade (MinGW 6.0.0 with GCC 8.1)
  • Formula interpreter upgrade (muParser 2.2.5)
  • Clearer indication when using the default fluid in models

Bug fixes

  • Model export did not perform the actual export process
  • Occasional mapping error in parameters of exported models
  • Simulation of exported models did not stop in case of error
  • Particle concentration in particle node could drop below zero
  • Component help "Cylinder" was incomplete
  • Capacity calculation in component "Hose Concentrated Parameters" was inaccurate
  • OPC interface could not be loaded

DSHplus Release 3.10

Changes

  • Modell export according to FMI 2.0 replaces tool-specific export interfaces
  • Parameterization of fluids via components instead of fixed data stored in DSHplus
  • Extended properties in the fluid data (Bunsen coefficient, vapour pressure)

Bug fixes

  • Models may not compile on Linux systems
  • Memory access error in pipe components with distributed parameters
