Meshing

General Meshing

New Features

Midmesh inspect tool
Midmesh inspect tool added under midmesh workflow. The tool identify/fix nodes deviating from the middle of the geometry, such as Nodes off middle, Nodes off solid edges, Nodes out of solid, Edges off solid edges, and Element centers off middle. The fix corrects the mesh to the mid by node movement or splitting elements.
New APIs
New API’s added for querying, updating and writing param and criteria file data individually or together.

Enhancements

Batchmesher

Feature capture improvements
Improved mesh flow for the geometry surfaces containing 180 folds.
Continuous improvements in mesh flow
Continuous improvements in mesh flow by reducing and adjusting the locations of tria elements near free edges, beads, holes and washers.
Waviness in mesh flow
Fixed issues with waviness in mesh flow on fillets.
Direct midmesh
Direct MidMesh through BatchMesher now respects the element organization specified in the parameter file.
Edit Elements Context
Split Sub-Context
Split Sub-Context: Continuous graphical spilt line support added also explicit element selection added, user could select elements by path via advance selection and perform the split action.
Move/optimize orphan mesh nodes
Move/optimize orphan mesh nodes supported along and across the feature edges (PLOTEL/1D's).
Improved smooth function
Improved smooth function and miscellaneous bug fixes done for Edit Elements functionalities.
Replicate Context
Extend/trim new mapping method
Extend/Trim new mapping method added, when there is no exact matching with the base this helps user to trim or extend their feature onto base.
Topology based 1d selection
Topology based 1d selection support added for Stitch/Extend edges with Alt + RMB button.
Improved move tool handling
Improved move tool handling and user experience, RMB and LMB clicks are mapped to easy reposition of the manipulator and move the copied feature to the destination reference point respectively.
Quick flip
Quick “Flip” option added in the micro-dialogue UI.
Miscellaneous
Time step criteria
Time step criteria added in legend for LS-DYNA and Radioss user profiles.

Solid Meshing

New Features

Solid Map tool in HyperWorks
Added a new “Solid Map” tool in meshing ribbon. This tool will allow user to find mappable solids and auto detect source and target. With this new tool, user will be able to define size on source surfaces and add biasing on source surface edges and along edges.

Enhancements

Enhanced fill hole algorithm
Enhanced fill hole algorithm to follow edge shape with higher angle.
Enhanced tetramesh remesh algorithm
Enhanced tetramesh remesh algorithm to remesh surfaces as well.
Auto split highly warped quads
Added capability to auto split highly warped quads to trias. Mostly used for airbag meshing.
Enhanced sliver fix capability
Enhanced sliver fix capability to remove slivers on non-manifold edges.

Resolved Issues

  • Segmentation error upon surface meshing with 2nd order quad mesh and then batch meshing
  • Segmentation error on running adaptive tria remesh with 1d and quad inputs
  • Remeshing elements crashed session with segmentation error
  • Make “Quad Only” option work for solidmap meshing
  • Twisted hexa elements are getting created for pipes
