We use a next generation CFD software system that uses a proprietary, particle-based, meshless approach which can easily handle traditionally complex problems.

This approach to CFD enables complex modeling and analysis in a straightforward way, minimizing the presence of algorithmic parameters and avoiding the traditionally time consuming meshing process.

Meshless approach

The meshless approach is particle-based and fully Lagrangian which means classic fluid domain meshing is not required and surface complexity is not a limiting factor. It can handle moving bodies and deformable parts, and is tolerant with the quality of the input geometry.

Particle-based kinetic solver

The softwate we use also features a novel particle-based kinetic algorithm that:
• Resolves the Boltzmann and the compressible Navier-Stokes equations.
• Features state-of-the-art LES (Large Eddy Simulation) modelling, and advanced non-equilibrium wall models.
• Has been specifically designed to perform very fast with accessible hardware.
• Provides Large Eddy Simulation (LES) analysis in CPU-times similar to most codes providing just RANS analysis.

Single consistent wall model

A unified non-equilibrium wall function to model the boundary layer. This wall model works in all cases, meaning that it is not necessary to select between different algorithms and take care of different limitations related to each scheme.

Near-linear scalable performance

Fast and efficient, even on a standard desktop PC. High performance computers are not required.

Advanced modeling capabilities

Can easily handle of large and complex models, and greatly simplifies the setup of analysis with:
• Moving parts
• Forced or constrained motion
• Contact modeling

Advanced analysis capabilities

XFlow's solver also features:
• Thermal analysis
• Conjugated heat transfer
• Flow through porous media
• Non-Newtonian flows
• Complex boundary conditions including the porous jump and fan models.

Adaptive wake refinement

The engine automatically adapts the resolved scales to the user's requirements, refining the quality of the solution near the walls and dynamically adapting to the wake while the flow develops.
