XFlow is a particle-based Lattice Boltzmann technology solver for high fidelity Computational Fluid Dynamics (CFD) applications. It offers multiphase and moving parts modeling capabilities with a special focus on lubrication workflows. XFlow features automatic lattice generation, GPU computing, and advanced rendering capabilities.

Irrespective of the system complexity, gear types, and lubrication methods, XFlow provides detailed insights into the system's performance. Lubrication simulation can reduce the number of physical tests and offers quantitative predictions for results like wetted area and churning losses that can be challenging to measure experimentally.

Automatic lattice generation in XFlow minimizes user inputs, reducing time and effort in the meshing and pre-processing phase. XFlow provides comprehensive GPU computing support to expedite the solution time. Problem setup and results exploration are easy and intuitive, enabling users to focus their efforts on design iteration and optimization. In addition, advanced rendering capabilities provide realistic visualization to gain deeper insight into flow performance.

The state-of-the-art technology of XFlow for lubrication enables users to address other related CFD workflows involving high-frequency transient simulations with real moving geometries, complex multiphase flows, and free surface flows.

Beyond Lattice Boltzmann

In non-equilibrium statistical mechanics, the Boltzmann equation describes the behavior of a gas modeled at a mesoscopic scale. Unlike standard Multiple Relaxation Time (MRT), XFlow implements the scattering operator in central moment space, which naturally enhances the Galilean invariance, accuracy, and stability of the code.
