Mesh

class hoomd.mesh.Mesh

Data structure combining multiple particles into a mesh.

The mesh is defined by an array of triangles that make up a triangulated surface of particles. Each triangle consists of three particle tags and is assigned to a defined triangle type.

Example:

mesh_obj = hoomd.mesh.Mesh()
mesh_obj.types = ["mesh"]
mesh_obj.triangulation = dict(
    type_ids=[0, 0, 0, 0],
    triangles=[
        [0, 1, 2],
        [0, 2, 3],
        [0, 1, 3],
        [1, 2, 3],
    ],
)

types

Names of the triangle types.

Type: list [str]

triangulation

The mesh triangulation. The dictionary has the following keys:

• type_ids ((N) numpy.ndarray of uint32): List of

  triangle type ids.

• triangles ((N, 3) numpy.ndarray of uint32): List of triplets of particle tags which encodes the triangulation of the mesh structure.

Type: dict

property bonds

Mesh bonds.

A list of tuples of particle ids which encodes the bonds within the mesh structure.
