TotalSim is excited to expand our simulation capabilities with Altair ultraFluidX, a powerful addition to the CFD tools we offer clients. As a specialized GPU-native solver, ultraFluidX delivers transformative speed and efficiency for external aerodynamics and aeroacoustics simulations, particularly in automotive, motorsports, and transportation applications.
Built on the Lattice Boltzmann Method (LBM), ultraFluidX excels at capturing transient, unsteady flows, turbulence, and complex aerodynamic phenomena like drag, lift, and wind noise. Unlike traditional Navier-Stokes solvers, its inherently transient nature provides higher-fidelity insights into real-world bluff-body aerodynamics without compromising on turnaround time.
Standout Advantages
- GPU-Native Performance: Fully optimized for NVIDIA GPUs, ultraFluidX slashes simulation times from days or weeks to overnight runs — even for full-vehicle models — on a single server or multi-GPU setup. This enables rapid design iteration and exploration of hundreds of variants.
- Automated Pre-Processing: Robust automated wrapping and gap-filling technologies in HyperMesh CFD eliminate tedious manual meshing, dramatically accelerating workflows.
- Practical Applications: Ideal for vehicle drag reduction, crosswind stability, aeroacoustics (wind noise), underhood flows, and environmental aerodynamics around buildings.
How ultraFluidX Complements the Siemens/Altair Suite
Within the broader Altair CFD portfolio (which includes general-purpose AcuSolve and SPH-based nanoFluidX), ultraFluidX stands out as the go-to solution for high-speed external aero. While AcuSolve offers versatile, implicit Navier-Stokes capabilities for a wide range of multiphysics problems (thermal, internal flows, FSI), ultraFluidX provides unmatched speed and automation specifically for transient external aerodynamics.
When paired with Siemens tools like Simcenter STAR-CCM+ (which TotalSim also supports as a reseller), ultraFluidX serves as a high-throughput complement. Use it for early-stage design sweeps and rapid concept evaluation, then leverage STAR-CCM+ or AcuSolve for deeper multiphysics validation. This hybrid approach maximizes productivity while controlling costs.
For TotalSim clients, ultraFluidX means faster insights, more design iterations, reduced physical testing, and accelerated time-to-market—especially valuable in competitive motorsports and automotive development. Contact us to explore how ultraFluidX can integrate into your workflow.
