If you are designing a static wing for a commercial airliner flying at Mach 0.85, stick with Ansys Fluent or STAR-CCM+. The established FVM ecosystem is mature and efficient.

: Say goodbye to traditional mesh generation. XFlow’s approach significantly reduces pre-processing time, allowing you to focus on the physics rather than the grid.

| Feature | Traditional CFD (FVM) | XFlow CFD (LBM) | | :--- | :--- | :--- | | | Manual, time-consuming, requires skill | Automatic, octree-based, seconds | | Moving Parts | Sliding mesh or overset grids (complex) | Natural (moving walls via particle resetting) | | Free Surface | VOF with interface reconstruction (diffuse) | Sharp interface, particle tracking (sharp) | | Simulation Speed | Fast for steady-state | Fast for transient, noisy for steady-state | | High Mach No. | Excellent | Limited (LBM works best low-subsonic) | | Boundary Layers | Prism layers required | Wall functions or near-wall refinement |

Unlike traditional solvers that discretize macroscopic Navier-Stokes equations, XFlow solves the Boltzmann equation
