General Purpose CFD

General-purpose CFD

Altair CFD’s Navier-Stokes solver includes a full range of flow, heat transfer, turbulence, and non-Newtonian material analysis capabilities. It provides companies with a solution that is robust, scalable, and accurate regardless of the quality and topology of the mesh elements. A dedicated and streamlined workflow is available in Atair ® HyperWorks® – including pre-processing, solver execution, and post-processing all under the same interface.

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

External Aerodynamics

Aerodynamics and Aeroacoustics

Altair CFD’s Lattice Boltzmann method (LBM) solver enables 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. This revolutionary technology also allows for direct calculation of aeroacoustics from rotating machinery such as cooling fans, e-motors and renewables.

Particle-based Fluid Dynamics

Particle-based Fluid Dynamics

Altair CFD’s smooth particle hydrodynamics (SPH) solver is used to predict fluid flow around complex geometries under complicated motion. This method has significant benefits when looking at any free surface (liquid/air) flows in terms of both time and accuracy.

Discrete Element Modeling

Discrete Element Modeling

Altair EDEM™ is a discrete element method (DEM) software that accurately simulates and analyzes the behavior of granular materials such as coal, mined ores, fibers, grains, tablets, and powders. Using CFD coupled with EDEM enable engineers to realistically simulate the interaction between fluid and particles and to investigate a range of complex systems such as fluidized beds, solid-liquid mixing, spray coating, filtration, and drying.

Thermo-fluid Systems

Thermo-fluid Systems

Altair® Flow Simulator™ 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 has been originally developed as 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.

Electronics Cooling

Electronics Cooling

Altair® SimLab™ is a process-oriented multidisciplinary simulation environment to accurately analyze the performance of complex assemblies. SimLab includes a range of highly automated workflows enabling the electronics industry to confidently identify and correct potential design issues earlier in development with thermal analysis that does not require advanced CFD knowledge. This includes the capability to simulate challenging electronics cooling and other electronic design automation (EDA) thermal management applications
