mesh.Mesh.split_by_angle#

Mesh.split_by_angle(angle=60.0, sort='number')#

Split a tri3 Mesh by splitting it at sharp edges.

This is like partition_by_angle() but returns a list of partial Meshes. The parameters are like in partition_by_angle()

Returns#

list of Mesh: A list of Meshes that each form a connected part. By default the parts are sorted in decreasing order of the number of elements.

Examples#

>>> coords = Coords([[0.0, 0.0, 0.0],
...                  [1.0, 0.0, 0.0],
...                  [0.0, 1.0, 0.0],
...                  [0.0, 0.0, 2.0]])
>>> elems = [[0,1,2], [0,2,3]]
>>> M = Mesh(coords,elems,eltype='tri3')
>>> M_split = M.split_by_angle(sort='area')
>>> print(M_split[0])
