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.
