About Dassault Systemes Simulia XFlow. Dassault Systèmes' acquisition of XFlow compliments SIMULIA's existing capabilities in Computational Fluid Dynamics (CFD) in an exceptional way. We have already built up strong applications for steady flow based on the predominant NavierStokes approach. XFlow goes beyond these existing technologies to the different Lattice Boltzmann methodology that is preferred by most users for highly dynamic, or unsteady, flow.
Unsteady flow often arises with flow across complex solid geometries, such as the exterior surface of an automobile. A traditional mesh-based approach to these problems is highly dependent on the quality of the mesh-so that engineers have to spend significant time working on mesh discretization. Difficulties can arise when there are changes in the topology of the domain for problems involving the presence of moving parts or fluid-structure interaction. XFlow's meshless particlebased methods reduce the traditional time-consuming meshing burden, enabling engineers to focus the majority of their efforts on design iteration and optimization.
With XFlow's discretization approach, surface complexity is not a limiting factor. The underlying lattice can be controlled with a small set of parameters; the lattice is tolerant to the quality of the input geometry and adapts to the presence of moving parts. XFlow's kinetic solver has been specifically designed to perform very fast with accessible hardware. The solver also features, adaptive wake refinement for proximity to walls, high-fidelity turbulence modeling, thermal analysis, porousmedia flow, non-Newtonian flow, a fan model and more.
XFlow supports behavior prediction and improves performance of many different kinds of complex designs subjected to unsteady flow. In addition to aerodynamic flow past a vehicle, these can include aerodynamic noise from aircraft landing gear and lubrication of complex drivetrains. This technology continues to improve automobile fuel economy and emissions, reduce the environmental noise of aircraft, and increase the efficiency of wind turbines, among many industry applications.
