Altair® Twin Activate™

Converging Multidisciplinary System Simulation with Digital Twins

Altair® Twin Activate™ is an open and flexible integration solution that enables whole system simulation with real-time digital twin deployment through any stage of the product lifecycle.

Through a unique block-diagram modeling environment, teams can model systems and systems-of-systems of any complexity. They can then test and predict system performance under various conditions using Altair’s digital twin solution that converges multidisciplinary, multiphysics simulation with revolutionary artificial intelligence (AI), data analytics, and high-performance computing (HPC) technologies.

Twin Activate’s purpose-driven simulation capabilities facilitate mixed-fidelity modeling that helps teams define simulation areas of interest. This efficient approach saves time and resources while quickly generating the most meaningful analyses possible. What’s more, unparalleled collaboration is the key; teams from different engineering domains can contribute to the same source models, incorporate existing workflows, eliminate information bottlenecks, and gain deeper, actionable insights faster.

Key Features

1D System Simulation

Simulating at the system-level is much faster than 3D simulation and enables complete product performance assessment. Relying on greater levels of model abstraction enables rapid design exploration and deeper performance insight early in the design cycle.

Block Diagrams, Control System Design

The intuitive block-diagram modeling environment enables easy development of today's smart systems involving sensors, actuators, feedback, and built-in logic.

Mix Signal-Based and Physical Modeling Within Diagrams

Leverage the power of pre-defined Modelica libraries for modeling common mechanical, electrical, hydraulic, and thermal components.

Code Generation

Compile models into executable code that captures dynamic behavior; use the code for a variety of applications: block customization, exporting to other simulation environments, standalone Windows and Linux applications or specific targets such as Arduino, and more.

Seamless Integration with Other Altair Tools

True multidisciplinary system simulation is possible via co-simulation with Altair® MotionSolve® for controlled multibody dynamics, Altair® Flux® for controlled motor performance, and Altair® PSIM™ for power converter and motor drive simulation.

Import and Export Support for Functional Mock-Up Interface (FMI)

Enables model exchange or co-simulation connections to all tools that support the FMI standard.
