Altair AcuSolve 2022.2 Release Notes

Highlights

  • AcuSolve/EDEM 3-phase
  • AcuTrace ribbon in HyperWorks CFD

New Features

AcuSolve/EDEM 3-Phase
Three phases may now be simulated when coupling AcuSolve with EDEM. Particles are modeled in one phase, a liquid could be modeled in the second phase, and a gas can be modeled as the third phase, for example. As many manufacturing or process-related design simulations require including both a liquid and air along with particles, this new capability widens the range of application for this unique coupling. Surface tension input should be defined and the behavior due to the contact angle definition will be respected for all three phases.

Enhancements

AcuTrace
The particle tracking tool, AcuTrace, previously only available from the AcuConsole interface, has been introduced as a ribbon in the HyperWorks CFD interface. This implementation supports sequential simulations of massless particles or particles with mass, static and dynamic flow fields, and mesh motion. The static mixer tutorial has been updated for the HyperWorks CFD workflow as well.
Topology Optimization Updates
Additional constraints can be set on outlet boundaries during a topology optimization simulation allowing you to specify the desired mass flow out of each. Flow can be balanced across all outlets or based on your needs. A strength parameter is now available which impacts how the optimizer determines the minimum volume needed to deliver the fluid.
Binary Results File Conversion Utility
You are now able to convert your existing AcuFieldView binary format (.fv) results files to HyperWorks binary (.h3d) results file format with the acuFv2H3D script. The H3D format is readable by all Altair post-processing tools.
Log File Updates
You may not be aware that surfaces selected for symmetry conditions are non-planar. A message is now written to the Log file suggesting that you inspect the geometry if the surface is expected to be planar or to consider setting a slip condition instead.
