Fluids and Thermal

Whether you’re an analyst performing advanced computational fluid dynamics (CFD) modeling or a design engineer who quickly needs to understand fluid or thermal effects on a design proposal, Altair offers a complete line of tools to support your project. From detailed component analysis to full systems performance, Altair provides a range of scalable solvers and robust pre- and post-processing software for CFD.

General Purpose CFD

Altair AcuSolve™ is a proven asset for companies looking to explore their designs providing a full range of flow, heat transfer, turbulence, and non-Newtonian material analysis capabilities without the difficulties associated with traditional CFD applications. AcuSolve® is robust, scalable, and accurate regardless of the quality and topology of the mesh elements.

No CFD software gets you to your end goal sooner: analyzing results and exploring the physics of your product.


External Aerodynamics

Altair ultraFluidX™ was developed specifically for ultra-fast prediction of the aerodynamic properties of passenger cars, light trucks, race cars, and heavy-duty vehicles. Its cutting-edge technology is optimized for energy and cost-efficient GPU-based computing to deliver unbeatable performance and to allow for overnight simulations of even the most complex models on a single server. Combined with Altair Inspire Studio in the early concept design phase, ultraFluidX® enables rapid iterations for fast decisions.


Particle-based Fluid Dynamics

Altair nanoFluidX™ is a particle-based hydrodynamics (SPH) tool to predict fluid flow around complex geometries under complicated motion. A major application is to simulate oiling within both conventional and electric vehicle powertrain systems comprising rotating shafts or gears. The analysis uses fast and efficient GPU-based computing to calculate forces and torques on individual components of the system. A simplified workflow makes modelling accessible to physical testing experts new to simulation.


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 can be coupled with computational fluid dynamics (CFD) software to investigate particle-fluid systems such as fluidized beds, solid-liquid mixing, spray coating, filtration, and drying.


Flow, Heat Transfer, and Combustion

GE’s Flow Simulator, exclusively distributed by Altair, is an integrated flow, heat transfer, and combustion design software that enables mixed fidelity simulations to optimize machine and systems design. Applicable to turbomachinery, automotive and energy, Flow Simulator is the unified fluid system design tool for GE Aviation’s engine thermal, combustion, lubrication, and fuel system design. It is rooted in decades of practical usage and experience, with aerospace-quality level validation and verification.


Multi-disciplinary Design Exploration

Altair 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. It is a direct interface to the most popular CAE solvers and enables the incorporation of multiphysics evaluations.
