Fluids Simulations to Improve Real-World Performance

What’s new in 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.
