- boundaryThe input MeshGenerator defining the output outer boundary
C++ Type:MeshGeneratorName
Unit:(no unit assumed)
Controllable:No
Description:The input MeshGenerator defining the output outer boundary
XYZDelaunayGenerator
Creates tetrahedral 3D meshes within boundaries defined by input meshes.
An input mesh will be used to define the outer boundary of a generated tetrahedral output mesh. Additional interior vertices can be automatically generated by specifying a desired tetrahedral volume. Additional interior boundary "holes" can be specified by the mesh generators specified in the "holes" vector parameter.
Each input mesh, as specified in the "boundary" parameter and optionally in the "holes" parameter, can define a closed manifold of boundary triangles either by including Tri3 elements for each triangle or by including volume elements whose external faces comprise the boundary manifold.
If multiple disconnected manifolds exist in a boundary mesh, only the manifold enclosing the rest of the mesh is considered to be "the" boundary. Input meshes which are not connected, which therefore have multiple outer boundary manifolds, are not yet supported.
Nodes internal to the boundary mesh are currently ignored. Future expansions of this class may allow such nodes to be retained as nodes in the output tetrahedralization.
Using stitching options, meshes used as "holes" can subsequently be stitched into those portions of the output mesh.
Interior vertices can be adjusted after mesh generation using the "smooth_triangulation" parameter, to produce a more "smooth" mesh, but currently the only mesh smoother option is a simple Laplacian smoother; this can have unwanted side-effects on meshes with concave boundaries or poor nodal valences, and so it is disabled by default for robustness.
The elements generated by XYZDelaunayGenerator can be refined according to a given uniform element volume specified as "desired_volume". This refinement is currently controlled by the third-party Netgen code.
