Product information

Altair Activate
Flexible tool for fast system modeling and simulation

Your 1D models can be built using either a signal-based method or a physical method (Modelica-based). You can also easily import and include other subsystem models defined as a Functional Simulation Unit (FMU) using the Standard Functional Simulation Interface (FMI).

Altair Activate is especially useful for simulating Wap smart mechatronic systems involving a combination of mechanical subsystems (like a plant model) and an electrical subsystem (like a modulator model) control) together with sensors & actuators.

Altair Activate is an open tool that allows you to model and simulate systems (including systems) using native 1D models in the form of a block diagram. It also offers the option of pairing 3D tools (like MotionSolve, Flux, FEKO, etc.) using a variety of approaches (e.g. co-simulation) - to emulate a true multidisciplinary system.

1. Benefits of using Altair Activate for system modeling and simulation

Improve system-level performance

Simulate and improve the dynamic behavior of multidisciplinary systems. Easily model, simulate, and validate intelligent systems where users can combine sensor, drive, and control functions from different components.

Development based on a leverage model

Activate provides a common framework for evaluating and communicating functionality throughout product development. Perform a system-level “what-if” analysis to quickly test multiple designs and monitor interactions of all components and subsystems covering the entire system.

Gain early insight into product-level functionality

Identify product-level problems early in the design process early and ensure that all design requirements are met. Activate provides users with a set of predefined standard blocks that can be easily combined with model systems. Activate users can easily take advantage of the large library of Modelica® physical components to further describe the device and controller.

2. Salient features of Altair Activate

Constructing visual diagrams

Drag, drop, and match patterns to quickly build models
Multi-window configuration with the ability to modify diagrams between windows using drag - drop and copy - paste
Supports simultaneous loading of multiple models in one session

Hybrid model

Model and simulate continuous and discrete dynamic systems

Multi-disciplinary model

Activate allows users to model and simulate the combined system behavior of real-world systems with support for a variety of fields such as Mechanical, Electrical, etc.

Co-simulate control models with multi-body models

Room temperature control system with Modelica components

Hierarchical and parametric model

Build models based on a real-world system hierarchy using the 1D block diagram modeling library
Combines physical model blocks and signal bases in the same model
When modeling large or complex systems, it is easy to create supermunks by aggregating multiple blocks in the diagram into a single block.
Super cubes are modular, reusable, can be concealed and function as basic as conventional blocks allowing for more flexibility
Since a model can be hierarchical and parameters can be defined at different levels, Altair Activate offers a 'all available parameters' option that allows the user to navigate within the diagram and get reports on all known or defined parameters at the current level.

Integrated block-based model library

Altair Activate includes a ton of predefined blocks available in an easy-to-use palette library. Users can also create their own custom blocks in C scripts or math in OML and save them to new or existing libraries.

Modeling of physical components using Modelica and SPICE

In addition to the signal-based blocks listed above, Activate comes with the standard library Modelica (MSL) - a set of blocks that describe the physical behavior of Electrical, Electromagnetic, Mechanical, and Thermal components. .

These blocks can be extended with user-defined Modelica blocks. Moreover, users can provide SPICE network list for modeling electrical circuits.

Librarian

Easily create components and assemble custom applications. Use Activate's Library Manager to create and edit custom libraries. Activate also provides an IDE along with API functions for users to further promote library management

Hybrid simulation

The Activate emulator provides users with a number of high-performance, precise, and powerful solvers of dynamic systems comprising continuous, discrete, and event-based behaviors.

Solver type	Stiffness	Solver name
Fixed step -size	Non – stiff ODE	Forward Euler Explicit Trapezoidal Classical Runge Kutta Runge-Kutta
Fixed step -size	Stiff ODE	Backward Euler Implicit Trapezoidal
Varible step-size	Non-stiff ODE	CVODE-BDF-Functional CVODE-ADAMS Functional DOPRI (Dormand-prince)
	Stiff ODE	Lsode CVODE-BDF-NEWTON CVODE-ADAMS-NEWTON RADAU-IIA for ODE CPODE
	DAE	IDA RADAUV-IIA for DAE DASKR

Optimization

Build optimization problems to improve system parameters and design powerful control strategies with multiple options.

Graphics optimization tools:

The easiest way to build and solve script-based optimization problems
A powerful mechanism for solving general optimization problems where costs and constraints can be obtained from combining Activate simulation results and BOBYA optimal mathematical script block
This optimization block can be used directly in a model and does not require any external calling or linking functions.
Layered optimized blocks to form maximum - minimum problems

Interchange and co-simulation over a Standard Interface (FMI)

Activate supports the FMI 2.0 standard for both model exchange and co-emulation of dynamic systems including the ability to import and export FMU (Function Test Model Unit)

Co-simulation with multi-object model

The co-emulation interface allows the user to simulate a complex system consisting of a multi-object system (MBS) and one or more control subsystems. To effectively simulate the entire system, MBS is simulated with a multi-object simulation solver while the control subsystem is simulated using Activate.

Linear

Activate allows users to create linear models from Activate blocks using linearization. The operating point can be calculated by running the simulation at a certain point in time or by calculating the stability point by imposing constraints on inputs, outputs, states and state derivation.

Compile the model into executable code

Activate supports creating code to protect system performance & IP
