Altair acquires FluiDyna to boost simulation capabilities


Following its initial investment in FluiDyna made in 2015, Altair has now acquired the company, a developer of NVIDIA CUDA and GPU-based CFD and numerical simulation technologies. FluiDyna’s simulation software products –ultraFluidX and nanoFluidX – are available to Altair’s customers through the Altair Partner Alliance and also offered as standalone licenses.

nanoFluidX is a fluid dynamics simulation tool that is useful for vehicle dynamics engineers. The system is based on the smoothed particle hydrodynamics method to predict the flow in complex geometries with complex motion – for example, it can be used to predict the oiling in differential systems, and to analyze forces and torques on individual components of the system.

The ultraFluidX package solves large-scale aerodynamics problems including prediction and evaluation of vehicle, building, and environmental aerodynamics. The software is based on the Lattice Boltzmann Method, which reduces the model preparation time for large, complex models, complemented by integrated volume meshing and fast transient analyses for short turnaround times.

In addition to continued growth and development of FluiDyna’s current product range, the acquisition is intended to help the technical teams of both organizations accelerate Altair’s broader offerings in CFD.
