In this age of the Internet of Things, Big Data, analytics and mechatronics it is the multi-disciplinary intersections of mechanical, electrical, and control systems that provide the product and experience opportunities the marketplace is striving for. Altair’s next generation math & system modeling solutions can be applied right from concept studies, control design, multi-domain system performance optimization to controller implementation & testing.

Model-based Development

Let us show you how.

Design, analyze and optimize the performance and behavior of multi-disciplinary, smart systems with Altair’s solidThinking model-based development software suite. This solution uniquely combines math with signal-based, physical and 3D modeling to offer a complete toolset that spans analog and digital circuit design through electro-mechanical system development.

Math Modeling & Numerical Analysis

A numerical computing environment for science and engineering

Leveraging a high level, matrix-based numerical computing language, our solidThinking Compose math modeling technology includes an interactive and unified programming environment for researchers and engineers to rapidly develop, debug and perform complex numerical computations to analyze and visualize data of all types.


The solidThinking Compose math engine - Open Matrix Language (OML) is not only compatible with GNU Octave but also provides a dual programming environment with Python and bridges between OML and Python. This allows for rapid algorithm development incorporating advanced math (OML) and advanced programming logic.

System Level

Altair provides a comprehensive solution for simulating C-code behavior for various chips and includes a very high-performance SPICE (Simulation Program with IC Emphasis) circuit simulator. Our MODELiis technology is used in Electronic Design Automation (EDA), system modeling, electromagnetics and sensor modeling of IoT devices.


Physical Level

Hybrid System Development

An intuitive block diagram environment for hybrid, multi-disciplinary systems development

Product creators, system simulation and control engineers can quickly model, simulate and optimize multi-disciplinary systems early in the design process with solidThinking Activate signal-based & physical component modeling technology.


With extensive discrete, time-continuous signal-based block libraries, robust solvers, native support for various Modelica physical component block libraries along with Functional 

Mock-up Interface for model exchange and co-simulation, solidThinking Activate delivers a modern user experience for developing hybrid systems with the unique ability to mix signal-based and physical components in the same diagram.

Altair’s solidThinking Embed technology provides a complete toolchain for the development of embedded control systems covering Software-in-the-Loop, Processor-in-the-Loop as well as Hardware-in-the-Loop simulations.


With automatic C-code generation, solidThinking Embed streamlines the entire embedded systems development process with ability to interactively change control diagrams, auto generate high efficiency C-code, compile and download it to the target MCU in seconds.

“solidThinking Embed allowed us to model the system and be confident about our design before committing to any hardware. The software guided us in the right path to take and sped up development.”
