Key Features & Benefits
With ultraFluidX, highly resolved transient aerodynamics simulations can be performed overnight on a single server. The benefits in detail are:
Fast and easy case setup
Thanks to seamless integration into the Altair Virtual Wind Tunnel, setting up an external aerodynamics simulation becomes trivial. Templates can be derived quickly for different vehicle classes, making the workflow less prone to errors.
Short turnaround times enabling overnight runs
The Lattice Boltzmann Method is a perfect fit for massively parallel architectures like GPUs, and sets the stage for unprecedented turnaround times. Overnight runs on single servers become possible by utilizing state-of-the-art GPU optimized algorithms, while delivering the fidelity of a transient LES aerodynamics simulation.
Minimum pre-processing effort
Profit from the “Drag and Drop” nature of this Lattice Boltzmann implementation. Low surface mesh requirements, support for intersecting and penetrating parts, together with a fully automated volume mesh generation in the solver, make part replacements easier than in the wind tunnel.
Bluff body aerodynamics, and especially vehicle aerodynamics, are highly unsteady by nature. With ultraFluidX well-resolved transient LES simulations become affordable. No need to press transient physics in a steady-state corset anymore.
Significant cost savings
Conventional simulation approaches need thousands of CPU cores to achieve the turnaround times of ultraFluidX. Our GPU based solution increases throughput while reducing hardware and energy cost.

Post-Processing of the transient flow field
ultraFluidX is ideal for external aerodynamics investigations of ground transportation vehicles in a wide range of operating conditions.
- Transient flow analysis: Determine aerodynamic forces and moments (e.g., drag, lift, roll, pitch, yaw) and investigate separated flow regions and vortices.
- Reducing fuel consumption: Minimize the aerodynamic drag.
- Improving driving stability: Balance front and rear lift and investigate the crosswind behavior.
- AEC (Architecture, Engineering and Construction): Analyze wind loads on buildings and the propagation of pollutants.
