XFlow

Fluids Simulations to Improve Real-World Performance

What’s new in 2022

  • Ability to plot pressure and viscous force/moment contributions separately.
  • XFlow now supports AMD GPU cards with Linux operating systems.
  • XFlow now performs several checks to prevent IB bodies crossing levels.
  • Ability to compute the time averaged data from a starting time step.
  • Ability to save a reduced amount of scalar, surface and volumetric fields as either instantaneous values, averaged values or both.
  • Enhancements on torque and force results for Free Surface and Particle-based solvers.
  • Mass flow controller corrects the mass flow to assure the right value when the ratio between the lattice size and the geometry tesellation is too large.
  • Enhancement on velocity outlet boundary condition (BC) for the Particle-based solver to allow the exit of a mixture of both phases.
  • Reduced GPU memory consumption in cases with moving parts or multi-resolution.
  • Simulation log file includes more information in a structured format.
  • Probes are now available.
  • Solver Surface Integrals are available with “Sum” and “Average” type.
  • 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.
  • 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.
  • 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.
  • 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.
