LUND, Sweden, Jul 2, 2021 – Modelon is pleased to announce the release of Modelon Impact systems modeling and simulation software, version 2021.2.
Key Highlights:
3D Animation Support
- Out-of-the-box support
- Improved selection of objects – including hiding objects to allow selection of objects inside
- 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
- Support for experiments with ‘structural parameters’ using range () and choices () operators
- Automatic scheduling and parallelization of compilations
Improved Modelica code editor
- Quickly navigate to a class using hyperlinks – Navigate back and forth with arrows
- Improved readability
- Theme selection – use a dark or light theme
- Code folding – annotations are folded
- Bracket matching – see where code block start and end
- Block comments – comment and uncomment code
- Word wrap – long lines are wrapped into multiple lines
Library browser filter
- Filter as you type with instant feedback
- 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.
- 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
- 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
- Resolve issue – Manually resolve issues in the code editor. The editor helps indicate where the issue is
Local equation balance checker
- Quickly verify that an equation system is locally balanced.
- A local balance check verifies that the number of equations and variables match up assuming sub-components are balanced
Additional features and enhancements
Performance:
- Simulation speed-up – reduced overhead when executing from UI
- Improved symbolic manipulation – can in special cases reduce the size of equation systems which improves simulation performance.
- Support for Modelica inverse annotation – can improve simulation speed and robustness.
Usability:
- Plotting improvements
- Customize colors
- Select a trajectory or result point and modify the colors using a plot UI
- Color settings can be saved to views
- Multi-color mode for parameter sweeps
- Units on the Y-axis
- Customize colors
- Improved source-code formatting
- Duplicating a model now preserves formatting.
- Improved compiler error messages for failed size evaluations
- Improved diagnostics for encrypted models – easier to debug models including encrypted components.
- View results of canceled simulations
- Improved support for redeclared components
- Unit settings support at experiment setup – easier to setup experiments on a larger time scale
- Support for Modelica annotation HideResult
Model utilization:
- Improved optimization toolchain – support for more Modelica constructs in the Casadi-toolchain
- Support of external functions, functions with unknown sizes, nested functions with unknown sizes, enumerations, better handling of if-statements
- Increased the performance of CasADi transfer by around 60% for large models
- New solver for CS FMU export – Runge-Kutta (2nd order).
- Custom function improvements – option to specify if a pre-compiled FMU is not required.
