Altair Activate™

Multi-Disciplinary System Simulation

What is Altair Activate™?

Altair Activate software is an open & flexible tool for rapidly modeling and simulating products as multi-disciplinary systems in the form of 1D models (expressed as signal-based or physical block diagrams), optionally coupled to 3D models.

Leverage a flexible spectrum of simulations throughout your development cycle – ranging from early concept design (with models involving more abstraction and typically shorter simulations) to later detailed design (with less model abstraction & longer simulations).

Other products in Altair's Model-Based Development offering include Altair Compose™ and Altair Embed™.

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 & subsystems.

Better Insight, Faster

Gain an increased understanding of your product’s performance by incorporating multi-disciplinary aspects in your system simulations (e.g., mechanical & electrical; fluids & structures; electromagnetic and thermal effects; etc.), including coupling 1D and 3D models.

Open & Flexible

Powerful built-in functionality is further extended by use of open standards such as Modelica and FMU. Complements, and works well with, Altair’s broad suite of engineering simulation software (e.g., MotionSolve, Flux, FEKO, etc.)

Altair Activate 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

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

Mix Signal-based and Physical Modeling in Same Diagram

Leveraging the power of pre-defined Modelica libraries for modeling common Mechanical, Electrical, and Thermal physical components.

Typically much Faster than 3D Simulations

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

Connections to Other Altair Tools

Enabling true multi-disciplinary system simulation via model exchange or co-simulation with MotionSolve for controlled multi-body dynamics, with Flux for controlled motor dynamics models, etc.

Support for Functional Mockup Interface (FMI)

Including Functional Mockup Units (FMU) enables model exchange or co-simulation connections to non-Altair tools which also support the FMI standard.
