Every 6 months, Distene delivers a new release of MeshGems. Highlights of the MeshGems 2.10 of Autumn 2019 are the following:
– 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.
- Improvement of the quadrilateral surface meshing capabilities
– New features
- Anisotropic 3D proximity
- 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.
