XFlow is next-generation computational fluid dynamics software built on a mesh-free Lattice Boltzmann Method (LBM). It enables engineers to simulate highly transient, multiphase, and free-surface flows — even in the presence of moving parts and complex geometries — with unmatched speed and flexibility.
Designed for advanced CFD applications across automotive, aerospace, industrial equipment, energy systems, and lubrication-intensive systems, XFlow delivers detailed insight into performance-critical fluid interactions without the burden of traditional meshing workflows.
