14.2. New Features in TGrid 14.0

CutCell Meshing

The following CutCell enhancements have been made in TGrid 14.0:

  • General improvements have been made in the areas of feature capturing, cell sorting and quality.

  • Fluid and Dead CutCell zones can be automatically separated using material points. The main advantage is the ability to extract flow volumes from surrounding solid CutCell objects and capping faces.

  • Material points can be created, listed, and deleted.

  • After material point based separation, the remaining dead and solid cell zones can be automatically deleted.

  • Overlapping boundaries between CutCell objects are properly resolved into a single interior zone and renamed based on object priority.

  • Sharp trailing edges and thin regions can be resolved using two separate commands for faces and edges.

Prism Meshing

The following prism meshing enhancements have been made in TGrid 14.0:

  • Special corner treatment has been added to improve CutCell prism quality.

  • Speedup of the prism generation up to a factor of two depending on the number of layers created.

  • Improved quality and stability of mesh morphing as part of Cutcell prism generation.

Cut-Tet Meshing Workflow

The Cut-Tet workflow is a new approach to create a tetrahedral, hexcore, or prism mesh based on a triangulated and improved CutCell surface mesh.

Miscellaneous Enhancements

The following miscellaneous enhancements have been made in TGrid 14.0:

  • Edge operations:

    • An improved algorithm for creating the intersection edge results in a speedup by a factor of 2 or more.

    • The ability to delete small edges has been added.

  • Tetrahedral Meshing Enhancements:

    • Tetrahedral meshing robustness has been improved.
