XFLOW – FLUIDS SIMULATIONS TO IMPROVE REAL-WORLD PERFORMANCE
XFlow is a particle-based Lattice Boltzmann technology solver for high fidelity Computational Fluid Dynamics (CFD) applications as a part of SIMULIA’s Fluids Simulation portfolio. XFlow offers multiphase and moving parts modeling capabilities specially focused on lubrication workflows such as gearboxes and electric motor drives.
Regardless of the system complexity, gear types or lubrication method, XFlow provides detailed insight into the system performance. Lubrication simulation can reduce the number of physical tests, and it provides quantitative predictions for results like wetted area and churning losses that can be very difficult or impossible to measure experimentally.
XFlow’s automatic lattice generation minimizes user inputs thereby reducing time and effort in the meshing and pre-processing phase. XFlow fully supports GPU computing to accelerate the time to solution. Problem setup and results exploration are easy and intuitive, enabling users to focus their efforts on design iteration and optimization. In addition, advanced rendering capabilities provide realistic visualization to gain deeper insight into flow performance.
The state-of-the-art technology of XFlow for lubrication enables users to address other related CFD workflows involving high frequency transient simulations with real moving geometries, complex multiphase flows and free surface flows.
what is new in XFlow 2022
New GPU features:
- Probes are now available.
- Solver Surface Integrals are available with “Sum” and “Average” type
*Velocity and VOF fields only
- Contact angle hysteresis is now available in Phase Field solver
- Isotropic and anisotropic porous media is available for fixed geometries
- Turbulence model selection is now available in GPU with Smagorinsky and WALE turbulence models
- Support for new boundary conditions: convective outlet, mass flow inlet and outlet, and porous wall inlet (phase field only)
- Linux version support is now upgraded to CentOS 7. This means the minimum required CentOS/RHEL version is 7 or greater. Upgrade of your Linux distribution may be required.
- The function insidegeometry() is now supported in GPU.
- The Water Channel has been redesigned for GPU for Free Surface and Multiphase Particle-Based tracking solvers and includes the following new inputs: Free surface level, Current velocity, Wave inlet: Disabled/Regular Linear Theory (Airy) is included with the wave length and wave height inputs
- GPU simulations, also available in Preferences > Engine.
- New option -m or –maxcore to limit the number of GPU Streaming Multiprocessors SM’s Streamline Multiprocessors
- CATpart and CATproduct importation now allows to import visualization geometries
- The Solver Surface/Volume Integrals now support immersed-boundary geometries and geometries with disabled boundary conditions
- Solid geometries in Conjugate heat transfer can now be used as the internal domain bounding geometry
- Keyframes are saved when using the “Save as” function
- Animated geometries are now supported as Post-Processing shapes even with loaded data
- Moving porous media pressure drop has been improved now following correctly the Darcy-Ergun law
- Support for new SIMULIA Unified licenses (SIMUNIT) that allow running any SIMULIA products with the same license: Tokens and Credits
Tokens: allocated during use and released after use.
Credits: consumed during the use.
- New License section in the Preferences allows switching to different license servers (DSLS, RLM) and license types (XFlow Tokens, Universal License Tokens, Unified License Credits).
- Moving porous media are now supported.
- Stability parameter have been introduced with three output modes:
Automatic: outputs all information when stability parameter >1.
Basic: outputs basic information when stability parameter >1, may be slightly faster than Automatic.
Off: not computed, may be faster in some cases.
- Rotational speed law for a body can be input in RPM for enforced motions.
