XFlow is a powerful CFD technology from Next Limit Technologies, a strategic partner of MSC Software, that uses a proprietary, particle-based, meshless approach which can easily handle traditionally complex problems in sectors such as engineering, design, science, and architecture.
XFlow provides the ability to simulate the flow of gases and liquids, heat and mass transfer, moving bodies, multiphase physics, acoustics and fluid structure interaction. The XFlow 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.
For engineers and analysts who require quick and accurate feedback on flow, thermal, and acoustic behaviour, XFlow provides the following benefits:
XFlow dramatically improves the ´solution quality versus time-to-solution´ trade-off, lowering times and costs, and thus offering a real alternative to analysis in experimental facilities.
XFlow utilizes a proprietary particle-based approach to Computational Fluid Dynamics which is easy to set up and use, and which significantly reduces training and support costs.
XFlow's innovative approach allows complex problems to be solved on standard modern desktop computers, removing the need for large clusters or HPC systems.
XFlow's advanced techniques easily handle traditionally complex problems such as aero-acoustics, moving parts, free surface flows and fluid-structure interaction.
Key features of 2012 release include:
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.
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) modeling, and advanced non-equilibrium wall models.
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 or contact modeling.
Advanced analysis capabilities XFlow's solver also features thermal analysis, flow through porous media, non-Newtonian flows and complex boundary conditions including 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 fully parallelized for multi-core technology with near-linear scalability.
