Altair ultraFluidX
Super fast aerodynamic simulation solution
Altair ultraFluidX is a simulation tool for quickly predicting the aerodynamic properties of passenger and heavy vehicles as well as for sports racing applications. Advanced technology optimized for the GPU delivers outstanding performance and enables overnight simulation of even complex scenarios on a single server.
1. Aerodynamic simulation software benefits
With ultraFluidX, high resolution transient aerodynamic simulations can be performed overnight on a server. The detailed benefits are:
1.1. Setup simulation is quick and easy
Thanks to seamless integration into the Altair Virtual Wind Tunnel, setting up an external aerodynamic simulation is simple. Samples can be quickly retrieved for different vehicle types, making the workflow less error prone.
1.2. Simplify the pretreatment process
Benefit from the Drag and Drop nature of this Lattice Boltzmann method. Low surface mesh requirements, support for cross sections and penetrations, and fully automatic tick mesh creation in solver, make part replacement easier in physical wind tunnels. Evaluating hundreds of configurations to meet regulatory requirements becomes possible.
1.3. Fast design turnaround time
The Lattice Boltzmann method is suitable for continuous parallel architectures such as GPUs, and sets the stage for unprecedented turnaround times. Overnight running on single servers becomes possible using modern GPU optimization algorithms, while also providing the fidelity of transient LES aerodynamic simulation.
1.4. Significant cost savings
Conventional simulation method requires thousands of CPU cores to achieve the turnaround times of Altair ultraFluidX. Our GPU-based solutions increase throughput while reducing hardware and power costs.
1.5. Simulate with variable input conditions
Massive body aerodynamics, and in particular vehicle aerodynamics are unstable. With the well-resolved transient LES simulation of ultraFluidX becomes justified. There is no need to transient physical press in a steady state corset anymore.
2. Industrial applications of the nanoFluidX software
Altair ultraFluidX is specifically designed for high resolution studies of external aerodynamics, including the following selected applications:
2.1. Ground transportation in a wide range of operating conditions
Identify aerodynamic forces and timing (e.g. pull, lift, roll, throw, yawn) and examine transient three-dimensional flow structures to understand vehicle dynamics. Potential goals of the CFD analysis include minimizing aerodynamic drag to reduce fuel consumption as well as the balance of front and rear lift and investigating backwind behavior to improve stability. of the driver.
2.2. Personal customer application
Use ultraFluidX for your own use cases. Examining transient flow fields of different designs, for example, analyzing buildings and entire cities in a large-scale wind tunnel or studying the impact of local design changes on aerodynamic performance learning, such as evaluating the effects of local small-scale geometry changes on the trajectory flight of a soccer ball.
3. Features of the nanoFluidX software
