Unparalleled breadth of CFD simulation solutions

Altair CFD offers a comprehensive set of tools to solve fluid mechanics problems. Whether you are looking to perform thermal analysis of buildings, predict aerodynamics of vehicles, optimize gearbox oiling, reduce cooling fan noise, or develop innovative medical devices, Altair CFD can help.

Several methods are available, including:

  • A general-purpose Navier-Stokes (NS) solver for thermal and general-purpose applications

  • A smoothed-particle hydrodynamics (SPH) solver best suited for simulating free surface oiling, sloshing and mixing

  • A Lattice Boltzmann Method (LBM) solver for aerodynamics and aero-acoustics

These solutions are all available within a single license, enabling companies to address a wide range of applications while minimizing software expense.
