cellcomplex.property_topomesh.topological_operations.topomesh_flip_edge¶

cellcomplex.property_topomesh.topological_operations.topomesh_flip_edge(topomesh, eid, verbose=False, debug=False, loglevel=0)[source]¶

Perform an edge flip operation on a triangular PropertyTopomesh

The edge flip operation changes the vertices of a mesh edge to the two opposite vertices of its adjacent triangles. Thel local topological configuration has to be valid for the operation to be performed.

>>>  |\  |       |  /|
>>>  | \ |  -->  | / |
>>>  |  \|       |/  |
>>>  •---•       •---•

Parameters

topomesh (cellcomplex.property_topomesh.PropertyTopomesh) – The structure on which to perform the operation
eid (unsigned int) – The ID of the edge element to flip

Returns

Return type

None

Note

The PropertyTopomesh passed as argument is updated.

Warning

The PropertyTopomesh must be a triangular topomesh (cellcomplex.property_topomesh.analysis.is_triangular())
