Key Highlights:

3D Animation Support

  1. Out-of-the-box support
  2. Improved selection of objects – including hiding objects to allow selection of objects inside
  3. Export 3D animation as GLB format – GLB is a widely supported binary 3D-format that can be embedded into presentations

Parameter sweeps with  multiple compilations 

  1. Support for experiments with ‘structural parameters’ using range () and choices () operators
  2. Automatic scheduling and parallelization of compilations

Improved Modelica code editor 

  1. Quickly navigate to a class using hyperlinks – Navigate back and forth with arrows
  2. Improved readability
    1. Theme selection – use a dark or light theme
    2. Code folding – annotations are folded
    3. Bracket matching – see where code block start and end
    4. Block comments – comment and uncomment code
    5. Word wrap – long lines are wrapped into multiple lines

Library browser filter 

  1. Filter as you type with instant feedback
  2. Filter by model, package, or filename

FMU Co-Simulation Import 

Import a co-simulation FMU* and connect and simulate it with Modelica models. A common use-case is to import a controller developed in a 3rd party tool and connect it with a system model.

  1. FMU-import tool that automatically imports an FMU and generates a Modelica wrapper mode

*Support for CS-FMUs generated on the same Operating System that Modelon Impact runs on (Windows on Desktop & CentOS 7 at On-prem)

Support for working with libraries and models with syntax errors

  1. Import or load a library – Syntax errors show up as red dots in the package browser. Light red dots indicate a syntax error in a model inside a package
  2. Resolve issue – Manually resolve issues in the code editor. The editor helps indicate where the issue is

Local equation balance checker

  1. Quickly verify that an equation system is locally balanced.
  2. A local balance check verifies that the number of equations and variables match up assuming sub-components are balanced

Additional features and enhancements

Performance:

  1. Simulation speed-up – reduced overhead when executing from UI
  2. Improved symbolic manipulation – can in special cases reduce the size of equation systems which improves simulation performance.
  3. Support for Modelica inverse annotation – can improve simulation speed and robustness.

Usability:

  1. Plotting improvements
    1. Customize colors
      1. Select a trajectory or result point and modify the colors using a plot UI
      2. Color settings can be saved to views
      3. Multi-color mode for parameter sweeps
    2. Units on the Y-axis
  2. Improved source-code formatting
  3. Duplicating a model now preserves formatting.
  4. Improved compiler error messages for failed size evaluations
  5. Improved diagnostics for encrypted models – easier to debug models including encrypted components.
  6. View results of canceled simulations
  7. Improved support for redeclared components
  8. Unit settings support at experiment setup – easier to setup experiments on a larger time scale
  9. Support for Modelica annotation HideResult

Model utilization:

  1. Improved optimization toolchain – support for more Modelica constructs in the Casadi-toolchain
  2. Support of external functions, functions with unknown sizes, nested functions with unknown sizes, enumerations, better handling of if-statements
  3. Increased the performance of CasADi transfer by around 60% for large models
  4. New solver for CS FMU export – Runge-Kutta (2nd order).
  5. Custom function improvements – option to specify if a pre-compiled FMU is not required.
