Release note of Spring MeshGems 2.5

· MeshGems Release
Author

We did not release the MeshGems Newsletter of Spring 2017 and thus did not have the chance to present the new capabilities of version 2.5. This Newsletter is the occasion to fill this gap. Here are:

the New Features …

… in Surface Meshing

  • MeshGems-CADSurf: CAD/mesh parametric associativity data for the generated elements.

… in Mesh Processing

  • MeshGems-Cleaner: new parameter introduced to choose between various modes for the default settings. Two modes are currently available:
    • fluid for computational fluid dynamics cases,
    • structure for structural analysis cases.

… in Volume Meshing

  • MeshGems Infrastructure : Capability to create a crack inside a volume mesh in between domains.
  • MeshGems-Hybrid: the boundary layer size can now be specified on each surface tag relatively to the local surface element size.

and the improvements …

… in Surface Meshing

  • MeshGems-CADSurf: better quad-dominant meshing and self-intersection prevention algorithms,

… in Mesh Processing

  • MeshGems-Cleaner: the hole correction feature is now able to handle non-manifold holes.

… in Volume Meshing

  • MeshGems-Tetra: the robustness and success rate of the safe boundary regeneration mode have
    been noticeably enhanced for difficult geometries.
  • MeshGems-Tetra: the dependency of the results to the initial amount of allocated memory has been reduced.
  • MeshGems-Tetra HPC: the speed and robustness have been substantially enhanced on very complex
    geometries.
  • MeshGems-Tetra HPC: the memory localisation has been optimized in the multi-thread version. Allocated memory is now closer to the corresponding computing CPU core.
  • MeshGems-Hybrid: the speed of boundary layer generation has been noticeably increased.
  • MeshGems-Hybrid: the surface boundary layer elements existing in the input mesh are better taken into account.
  • MeshGems-Hybrid: the number of generated hexahedra over tetrahedra ratio has been slightly increased when using the hexa dominant mode.
