Autumn release 2.10 of MeshGems available : what’s new ?

· MeshGems Release

Every 6 months, Distene delivers a new release of MeshGems. Highlights of the MeshGems 2.10 of Autumn 2019 are the following:

Surface Meshing & Cleaning:

– New features

  • Capability to output the effective sizemap used for the surface mesh generation and pass it throughout the whole meshing workflow: can be reuse in another meshing step, and especially after a cleaning task when required, to preserve the same final mesh specification.
  • Possibility to split over-constrained surface edges when required by a solver constraint.
  • Option to relax the mesh quality and sizemap respect constraints in return for faster meshing process.
  • Anisotropic 2D proximity.

– Enhancements

  • Improvement of the quadrilateral surface meshing capabilities

Volume Meshing:

– New features

  • Anisotropic 3D proximity
Anisotropic 3D proximity available also in Volume Meshing

– Enhancements

  • Strong improvement of the quadratic multi-element meshing capabilities, including the quadratic boundary layer generation.
  • Sliver removal treatment significantly enhanced for further robustness
  • Improvement of the mesh regularity and quality


New “resilient” tetrahedral meshing technology available as a preview for beta testing:

  • Objective: Always be able to deliver a (tetrahedral) volume mesh from any, even dirty and faulty, input surface (triangle) mesh!
  • Ultimate solution for extremely bad inputs:
    • very dirty and faulty CAD geometries will lead to very dirty and faulty surface meshes and thus to failure of the volume meshing step and global workflow.;
    • when no failure of the global workflow is the priority, the “resilient” technology is mandatory.
  • Several modes to control the way the issues are treated and the quality of the resulting mesh.
