Represents an unstructured tetrahedral mesh in 3D.

The VolumeMesh class represents a 3D volumetric mesh, which consists of vertices and tetrahedral cells.

vertices¶

An array of vertices in 3D space.

Type:¶

np.ndarray

cells¶

An array of tetrahedral cells defined by vertex indices.

Type:¶

np.ndarray

markers¶

An array of markers or labels associated with th cells.

Type:¶

np.ndarray
