Altair ultraFluidX

Altair ultraFluidX is a specialized computational fluid dynamics (CFD) tool focused on external aerodynamics, particularly for the automotive industry. It leverages a GPU-based Lattice Boltzmann solver to provide rapid, transient simulations, enabling engineers to analyze full vehicle aerodynamics overnight on a single server. This performance helps aerodynamicists and designers quickly iterate through design options to optimize for low drag, which is critical for fuel efficiency and electric vehicle range. The software is part of the broader Altair suite, which has been acquired by Siemens. It features an intuitive workflow through a virtual wind tunnel for case setup. Pricing and specific deployment options are not publicly available and likely require contact with Siemens sales.
