mesh.Mesh.fuse

Mesh.fuse(parts=None, nodes=None, **kargs)

Fuse the nodes of a Mesh.

Nodes that are within the tolerance limits of each other are merged into a single node.

Parameters

parts: int array_like, optional

If provided, it is an int array with length equal to the number of elements that will be used to split the Mesh into parts (see split_prop()) and the fuse operation will be executed per part. Elements for which the value of nparts is negative will not be involved in the fuse operations.

nodes: int array_like, optional

A list of node numbers. If provided, only these nodes will be involved in the fuse operation. This option can not be used together with the parts option.

**kargs:

Extra arguments for tuning the fuse operation are passed to the coords.Coords.fuse() method.

Examples

>>> coords = Coords([[0.0, 0.0, 0.0],
...                  [1.0, 0.0, 0.0],
...                  [1.0, 0.0, 0.0],
...                  [2.0, 0.0, 0.0],
...                  [3.0, 0.0, 0.0],
...                  [2.0, 0.0, 0.0]])
>>> elems = [[0,1],[2,3],[5,4]]
>>> M = Mesh(coords,elems,eltype='line2')
>>> print(M.fuse())
