CM2 HexaMesh: Hex-dominant mesh generator
| |
Hexahedral meshing with CM2 HexaMesh® |
| |
CM2 HexaMesh is our most recent and most sophisticated mesh generator. Like the other unstructured meshers of the library, CM2 HexaMesh is a Delaunay-frontal mesh generator (mixed approach), making this mesher a robust and efficient tool for 3D solid mesh generation.
CM2 HexaMesh is a constrained mesher: it enforces the boundary mesh (all-quads, all-triangles or mixed) and, if any, all the internal prescribed (embedded) nodes, edges and faces.
CM2 HexaMesh is an hex-dominant mesh generator: it builds meshes with 8-node hexahedrons and (usually) 6-node wedges, 5-node pyramids and 4-node tetrahedrons in a conformal way. There is no quad-triangle junction inside the mesh: each intern element face is shared exactly by two jointed elements.
CM2 HexaMesh offers the same functionalities as the other meshers in CM2 MeshTools:
- Mesh mode or regularization mode (for an already existing 3D mixed mesh).
- Background mesh, growth rate (to control the mesh density inside the domain).
- Optimization level (to trade-off speed vs. elements quality).
- Colors of the elements (when the domain has several sub-domains).
- Neighbor matrix, quality histograms, interrupt handler, maximum allowable number of nodes...
As the rest of the CM2 MeshTools library, CM2 HexaMesh is written in optimized standard C++ and is 64-bit ready.
