2.3.3.3.71. NXcg_tetrahedron_set¶
Status:
base class, extends NXcg_primitive_set
Description:
Computational geometry description of a set of tetrahedra. ...
Computational geometry description of a set of tetrahedra.
Among hexahedral elements, tetrahedral elements are one of the most frequently used geometric primitive for meshing and describing volumetric objects in continuum-field simulations.
Symbols:
The symbols used in the schema to specify e.g. dimensions of arrays.
c: The cardinality of the set, i.e. the number of tetrahedra.
