The Altair development team is pleased to announce the availability of Activate 2022.0.0 is an open and flexible integration platform for comprehensive system-of-systems simulation.

New Features and Enhancements 2022.0

Release Highlights Extension Manager with Library Management
The Extension Manager lets you easily add, install, uninstall, and remove libraries.
- Location: File > Extension Manager:
- Quickly uninstall unwanted libraries from your Activate session. The libraries remain on your system and can be easily installed again with a simple toggle.
- Click a button to remove libraries that you no longer want associated with your Activate sessions.
- Install the Activate built-in State Machine and romAI* libraries on demand:

State Machine Library
This block library provides a methodology for constructing finite state machines. The library supports concurrent state machines and hierarchical constructions as well as run-to-completion and history features. Fully implemented into Activate, the library lets you leverage all features of the software including parameterization and code generation. Documentation and demos are provided.
romAI Library *
The romAI library helps you turn neural networks into Reduced Order Models that you can integrate into Activate, ioT and other platforms.

Time to Frequency Domain Utility
Displays data in a frequency domain for the Scope block. Select the Single-Sided Normalized FFT or Power Spectral Density option, then enter a sampling frequency in the Input Dialog.

× Altair Activate 2022.0 Close
A new window is generated with a frequency-domain plot and is named based on the primary scope window followed by FFT or PSD.

- Double-clicking a plot opens or closes the plot.
- Issue with the subplot Y axis not aligning is resolved.
- Display issue with plot windows with 6 subplots is resolved.
- Issue with deleting old signals from a Scope is resolved.
General Enhancements

Libraries

Machine Learning Library *
The Machine Learning library is comprised of a set of methods for predictive data analysis and is available in OML. The library features various algorithms for:
- Pre-processing
- Regression
- Classification
- Clustering
- Decomposition
- Distance calculation
- Evaluation metrics
- Model selection

Modelica
The embedded compiler TCC can now be used to run models, including Modelica models and all demos, therefore installing a Visual Studio compiler on Windows is no longer mandatory but is recommended.
HydraulicsByFluidon *
The following new components are available in the Hydraulics by Fluidon library:
Components for load sensing applications
- PropValve33LS: 3/3 proportional valve with additional LS port.
- PropValve33LSTableAx: 3/3 proportional valve with definition of cross section via look-up table and additional LS port.
- PropValve33LSTableQpx: 3/3 proportional valve with definition of flow vs. stroke and pressure difference via look-up table and additional LS port.
Volumes and pipes
- PistonAccumulator: Accumulator with a piston as separator between fluid and gas. In contrast to the bladder accumulator the piston has its own mass and dynamic.
- VolumeExt: Extension of the basic volume: the bulk modulus of housing is defined separately; the total bulk modulus is a combination of housing and fluid bulk modulus.
- Hose: Extension of pipe similar to VolumeExt: the bulk modulus of pipe wall is defined separately. In this way, a low stiffness of hoses can be taken into account.
Pressure valves
- PressureReducingValve: Model of a 2-port pressure control valve reducing the supply pressure to a desired level at working port.
- PressureControlValve: Model of a 3-port pressure control valve that not only reduces the supply pressure to a desired level at working port, but also limits the working pressure to the desired level.
- PropPressureControlValve: Model of a 3-port pressure control valve with an input of set pressure.
Flow valves
- TwoWayFlowControlValve: Model of a 2-way flow control valve maintains a largely constant outlet flow even at a variable (higher) inlet pressure.
- ThreeWayFlowControlValve: Model of a 3-way flow control valve maintains a largely constant outlet flow even at a variable (higher) inlet pressure. In contrast to a 2-way flow control valve, the 3-way flow control valve opens a discharge to the tank as soon as the set volume flow to the consumer is reached).

Additional Changes and Enhancements for the Libraries
- Display all errors raised by Spice in a single pop-up window.
- Support added for XNOR operation in the Logical block.
- FMU block optionally offers inner variables as output.
- New API to explode Super Blocks was added: bdeExplodeSuperBlock.
- Option added to set port label visibility from the GUI for Super Blocks.
- When getting the path of a file, both relative and absolute paths are now supported.
- The FromCSV block can read CSV files without a TIME column.
- Link names are now displayed in the Property Editor.

Additional Changes and Enhancements for the Documentation
- New tutorial for the Extension Manager.
- More content is available about installing libraries and managing libraries through the Extension Manager.
- Documentation of new solvers.
- API help can be displayed directly through help API name in the Command Window:

× Altair Activate 2022.0 Close
Activate is an open and flexible integration platform for comprehensive system of systems simulation. Based on a hybrid block diagram modeling environment for signal blocks, object oriented physical components, and electric and electronics systems, Activate allows multiphysics analysis throughout the development cycle.

The comprehensive support of math modeling, scripting and modeling languages, facilitate the re-use and integration of existing code within the same model. Multilevel modeling, using models of adjustable complexity, tool-independent Functional Mock-up Interface (FMI) standard, or co-simulation with Altair MotionSolve and Altair Flux facilitates multibody dynamics analysis for electromechanics sensors and actuator design.

Activate empowers the collaboration and closes the links between multi-disciplinary engineering that are often isolated in development silos.
