CFD Without Meshing
XFlow uses the Lattice Boltzmann method to simulate fluid dynamics without manual mesh generation. Complex geometries, moving bodies, transient flows — handled automatically.
Traditional CFD vs XFlow
Traditional CFD
- ✕Manual mesh generation (hours to days)
- ✕Geometry must be watertight and clean
- ✕Remeshing required for moving parts
- ✕Mesh quality directly affects accuracy
- ✕Complex setups for transient flows
XFlow
- Automatic lattice generation (minutes)
- Works with dirty/imperfect CAD geometry
- Moving bodies handled natively
- Lattice adapts automatically to flow features
- Transient analysis is the default mode
Lattice Boltzmann Method
Instead of solving the Navier-Stokes equations on a mesh, XFlow models fluid behaviour at the particle level using the Lattice Boltzmann equation. The computational domain is automatically discretised into a lattice of nodes — no manual mesh generation required.
The lattice adapts in real-time to flow features, refining where needed and coarsening elsewhere. This makes XFlow particularly powerful for problems that are traditionally painful to mesh: rotating machinery, free-surface flows, and geometries with small gaps and complex surfaces.
Fast Setup
Import CAD → define boundary conditions → run. Minutes instead of days.
Moving Bodies
Prescribed and free motion handled natively — no remeshing during simulation.
Any Geometry
Dirty CAD, non-watertight surfaces, tiny gaps — XFlow doesn't care.

No. XFlow uses the Lattice Boltzmann method which automatically generates a computational lattice around your geometry. This eliminates the traditional mesh generation step entirely.
XFlow is inherently transient. For quasi-steady results, you run the simulation until the flow stabilises. This approach captures phenomena that steady-state solvers miss.
XFlow supports STEP, IGES, STL, CATIA, SOLIDWORKS, NX, and other common formats. It handles non-watertight and imperfect geometry that would require cleanup in mesh-based solvers.
XFlow has a gentler learning curve than traditional CFD tools because it eliminates meshing. However, interpreting CFD results still requires engineering judgement. We offer training programs to get your team productive.
XFlow excels at problems involving complex geometry, moving bodies, and transient flows where meshing is traditionally difficult. ANSYS Fluent has broader model coverage for specialised physics. The right choice depends on your application.
