Altair Activate

Multi-disciplinary System Simulation

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

The comprehensive support of math modelling, scripting and modelling languages facilitates the re-use and integration of existing code within the same model. Multilevel modelling, 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.

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


What is Altair Activate?

Why Altair Activate?

Why Altair Activate?

Holistic Assessment

Simulate the performance of your entire product, including as a system-of-systems, to better assess overall behavior as well as interactions between components and subsystems.

Better Insight, Faster

Gain an increased understanding of your product’s performance by incorporating multidisciplinary aspects in your system simulations, including coupling 1D and 3D models.

Open and Flexible

Powerful built-in functionality is further extended by the use of open standards such as Modelica and functional mockup units (FMU). Altair Activate complements and works well with Altair’s broad suite of software.

Key Features

1D System Simulation

Simulating at the system level enables performance assessment of the complete product rather than only of a portion of the product.

Block Diagrams, Control System Design

Provides a natural modelling approach for developing today’s smart systems involving sensors, actuators, feedback, and built-in logic.

Mix Signal-based and Physical Modeling in the Same Diagram

Leveraging the power of pre-defined Modelica libraries for modelling common mechanical, electrical, hydraulics, and thermal physical components.

Much Faster than 3D Simulations

Relying on greater model abstraction levels enables more product-performance insight earlier (i.e., nearer the concept design stage) and rapid design exploration.

Connections to Other Altair Tools

Enables true multi-disciplinary system simulation via co-simulation with MotionSolve® for controlled multi-body dynamics, Flux for controlled motor dynamics models, etc.

Support for Functional Mockup Interface (FMI)

Including FMU enables model exchange or co-simulation connections to non-Altair tools, which also support the FMI standard.
