HyperWorks 12.0 Release Notes

CFD Tetramesh
• Auto collision detection for boundary layer growth: The boundary layer (BL) reduction step is now
included into the BL generation routine. During boundary layer generation a collision check is
performed and the boundary layer thickness is adjusted dynamically.
• Advanced parameters for boundary layer generation: Three new options to control the boundary
layer growth mechanism have been introduced, including a quality focused and a meshing time
focused set of predefined parameters. Selecting the user defined option will give access to several
boundary layer parameters which can be adjusted individually for each application.
OSSmooth 12.0 - Connectivity Detection
A new connectivity detection option is available when interpreting the results of a topology
optimization. This new option provides a more robust design interpretation process by capturing
important material distribution that could otherwise be missed due to the definition of a single density
threshold cut-off value.
OSSmooth 12.0 - Draw Recovery
The draw recovery option uses the draw direction input from a topology optimization setup to create
straight surface walls in the draw direction, in the isosurface interpretation.
OSSmooth 12.0 - Ply Shape Interpretation
Optimized ply shapes from a composite free sizing optimization can now be interpreted through
this option. During the interpretation process, the boundaries of the ply shapes are smoothened,
disconnected patches are created as separate ply entities, and options are available to treat very small
ply regions. Additionally, after the smoothing and interpretation process is complete, a ready-to-run
OptiStruct input deck is generated using the smoothened ply shapes and updated ply definitions, all
while preserving the material definition, properties and fiber orientation.
