Altair CFD Solvers 2026

It is a powerful suite of tools for solving complex fluid dynamics issues. Whether you're working on thermal analysis or aerodynamics, optimizing oil flow in gearboxes, reducing noise from cooling fans, or innovating in the medical device field, it provides the tools you need. This software package includes various solvers like Navier-Stokes (NS), Smoothed-Particle Hydrodynamics (SPH), and Lattice Boltzmann Method (LBM), ensuring you have the right approach for any challenge.

General-Purpose Navier-Stokes Solver

The Navier-Stokes (NS) solver is a versatile tool in the suite. It handles a wide range of thermal and general-purpose fluid dynamics applications. Whether you need to analyze a building's thermal performance or predict the aerodynamics of a new vehicle, the NS solver provides accurate and reliable results. This solver's adaptability makes it a cornerstone of its capabilities.

Smoothed-Particle Hydrodynamics Solver

The Smoothed-Particle Hydrodynamics (SPH) solver is particularly suited for simulations involving free surfaces. It excels in modeling oiling processes, sloshing effects, and mixing phenomena. This solver's particle-based approach allows for highly detailed and precise simulations of fluid interactions, making it ideal for applications requiring detailed surface behavior analysis.

Lattice Boltzmann Method Solver

The Lattice Boltzmann Method (LBM) solver is specialized in aerodynamics and aeroacoustics. It is excellent for predicting airflow around objects and analyzing noise generated by cooling fans or other aerodynamic sources. Its ability to simulate complex fluid flows and interactions with structures makes it an essential tool for optimizing designs and reducing unwanted noise.

One License, Multiple Solvers

One of the software's standout features is its unique licensing system. With a single license, you can access all the solvers and tools within the suite. This unit-based license system is scalable and easily deployable, offering a cost-effective solution for businesses of all sizes. This flexibility allows companies to address various applications without incurring the high costs typically associated with multiple software packages.
