Computational Fluid Dynamics (CFD) technology allows the analysis of flow behavior in virtual environments, lowering costs and times, and thus offering a real alternative to analysis in experimental facilities.
The XFlow approach to CFD analysis enables complex modeling in a straightforward way, minimizing the presence of algorithmic parameters and avoiding the traditionally time consuming meshing process.
Meshless approach
The meshless approach within XFlow is particle-based and fully Lagrangian which means classic fluid domain meshing is not required and surface complexity is not a limiting factor. XFlow can handle moving bodies and deformable parts, and is tolerant with the quality of the input geometry.
Particle-based kinetic solver
XFlow features a novel particle-based kinetic algorithm that resolves the Boltzman and the compressible Navier-Stokes equations. The solver features state-of-the-art LES (Large Eddy Simulation) modelling, and advanced non-equilibrium wall models.
The kinetic approach has been specifically designed to perform very fast with accessible hardware. It provides Large Eddy Simulation (LES) analysis in CPU-times similar to most codes providing just RANS analysis.
Advanced modeling capabilities
XFlow is capable of handling 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
XFlow's 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.
Single consistent wall model
XFlow uses 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
XFlow is fast and efficient, even on a standard desktop PC. High performance computers are not required. XFlow is fully parallelized for multi-core technology with near-linear scalability.
