Mechanical Systems and Controls

Altair® MotionSolve® performs 3D multi-body system simulations to predict the dynamic response and optimize the performance of products that move. By considering realistic motion-induced loads, environmental effects, and flexible bodies engineers and designers can be confident that their products, when made and operated, will perform reliably, meet durability requirements, and not fail from fatigue. MotionSolve drives multi-disciplinary product development teams by enabling the combined simulation of motion and control.

Advanced Electromagnetic Systems

Electric motors generate high frequency noise and vibrations. Altair® Flux® computes magnetic forces to be applied as loading conditions for noise, vibration and harshness (NVH) calculations using Altair® OptiStruct®. Design exploration with Altair® HyperStudy® can maintain motor performance while reducing the noise. Heat losses can also be calculated using Flux and used as initial conditions for Altair CFD™ to calculate temperature distribution. Multi-disciplinary simulations of antennas are also possible with Altair® Feko®.

Fluid-Structure Interaction (FSI)

FSI simulates the behavior of fluids and structures simultaneously. FSI methods in Altair® Radioss® are employed in airbag inflation, airplane ditching, and bird strike simulations. Through code coupling Altair CFD supports the FSI simulation of wind turbines, shock absorbers, offshore oil pipelines, blood vessels, racecar wings, and other complex systems, in addition to aeroacoustics problems. Altair CFD coupled with MotionSolve can also solve fluid-motion problems such as tank sloshing.

Thermomechanical Simulation

Thermomechanical simulation captures deformation and stresses in solids based on the combined effect of mechanical loading and thermal loading, including thermal expansion. OptiStruct has the capability to solve both the thermal and mechanical physics in a single simulation. This enables engineers to understand how automotive and aircraft engine parts behave under real world conditions. Other applications include printed circuit boards and heavy off-highway machinery.

Multi-disciplinary System Simulation

Altair® Activate® rapidly models multi-disciplinary systems as 1D models. By simulating the performance of an entire product engineers can understand overall behavior earlier and recognize key interactions between components and subsystems. Activate allows mixed signal-based and physical modeling including pre-defined libraries for mechanical, electrical, and thermal components. The powerful built-in functionality is extended by open standards such as Modelica and FMU to couple 1D and 3D models. The dynamic response of complex mechatronic systems can be quickly simulated, combining multi-body analysis mechanism with electrical and electronic subsystems.

Discrete Element Modeling

Altair® EDEM™ is the market-leading software for bulk and granular material simulation. Powered by industry-proven discrete element modeling (DEM) technology, EDEM quickly and accurately simulates and analyzes the behavior of coal, mined ores, soils, fibers, grains, tablets, and powders. EDEM couples with all of the major computer aided engineering (CAE) technologies such as finite element analysis (FEA), multi-body systems (MBS), and computational fluid dynamics (CFD).

Multi-disciplinary Design Exploration

HyperStudy is a multi-disciplinary design exploration, study, and optimization software for engineers and designers. Using design-of-experiments, metamodeling, and optimization methods, HyperStudy creates intelligent design variants, manages analysis runs, and collects data. Users are guided through the process to conclude data trends, perform trade-off studies, and optimize design performance and reliability. A direct interface to the most popular CAE solvers enables the incorporation of multiphysics evaluations.

Multiphysics Workflows with CAD Associativity

Altair® SimLab® is a process-oriented multidisciplinary simulation environment to accurately analyse the performance of complex assemblies. Multiple physics including structural, thermal, electromagnetics, and fluid dynamics can be easily applied using highly automated modeling tasks, helping to drastically reduce the time spent creating FEA models and interpreting results. The highly efficient, feature-based modeling approach allows the creation of templates to enable CAE automation of multiphysics analyses locally or in the cloud.

Massive Virtual Exploration

Altair® Unlimited™ boxes up software, system administration, and infrastructure-as-a-service into a single, intuitive platform. It is a turnkey, state-of-the-art private appliance, available both on-premises and in the cloud. Altair Unlimited delivers unlimited use of Altair solver software. To keep it working at maximum efficiency, HPC resource management and user-friendly web portal software is included with every system.

Altair Partner Alliance (APA) Solutions for Multiphysics

As you continue to explore real-world physical interactions with Altair multiphysics solutions, the APA offers additional multiphysics technologies to enhance product development activities.

RAMDO is a powerful tool for Altair simulation solution users to explore design reliability improvements by the formal inclusion of variability (materials, loads, manufacturing, operational conditions, and more) into simulations.

The APA also features a portfolio of multiphysics-enabled software to help improve how to predict and optimize physics-based designs and processes, all of which are available through your Altair Units license.
