Key Features Of Altair CFD

Multiple CFD Methods in One License
Altair CFD combines major CFD technologies in one licensed solution, giving engineers access to different solver methods for different classes of flow problems instead of forcing every application into a single approach.

High-Performance Solver Stack
The Altair CFD solver portfolio is optimized for high-performance computing, including GPU-based execution and scalable performance for large or demanding simulations.

Connected HyperWorks Workflow
Altair CFD solvers and supporting pre- and post-processing tools work through a common HyperWorks interface, helping teams move more cleanly from model preparation to results review and reporting.
Capabilities
General-Purpose Navier-Stokes Analysis
The general-purpose Navier-Stokes path supports flow, heat transfer, turbulence, and non-Newtonian material analysis, making it suitable for broad CFD and thermal applications.
Free-Surface and Multiphase SPH Simulation
The SPH solver is built for free-surface and multiphase behavior, especially where complex motion or extreme deformation matter, such as sloshing, mixing, and oiling studies.
Aerodynamics and Aeroacoustics with LBM
The LBM solver is geared toward rapid external aerodynamics and aeroacoustics, with support for vehicle, building, and environmental aerodynamics.
Steady-State and Transient CFD
Altair CFD supports both steady and transient solution strategies, enabling engineers to study stable operating conditions as well as time-dependent flow and thermal events.
CAD-to-Results Workflow in HyperMesh CFD
HyperMesh CFD supports the workflow from CAD import and geometry validation through boundary condition setup, meshing, solver launch, and post-processing in one streamlined environment.
Design Exploration and Automation
The workflow supports morphing, design changes, DOE studies, templates, utility scripts, and Python-based automation to help teams evaluate more design variants with less manual setup.
Post-Processing and Reporting
Altair CFD workflows include post-processing tools for visualizations and measurements, along with automated reporting capabilities for documenting geometry, result views, contours, slice planes, and animations.
Robust CFD on Unstructured Meshes
AcuSolve, the general-purpose CFD solver in the Altair CFD portfolio, is built on the finite element method and is designed for accurate, scalable solving on fully unstructured meshes.
