fedoo.Mesh.extract_elements

Mesh.extract_elements(element_set: str | list, name: str = '') → Mesh

Return a new mesh from the set of elements defined by element_set

Parameters:

• element_set (str|list) – The set of elements. If str is given, it should refer to an element set that exist in the dict: mesh.node_sets with the given key. If a list (or similar object) is given, it should contains the indices of the nodes.

• name (str, default: "") – The name of the new Mesh

Return type:

Mesh

Notes

• The new mesh keep the former element_sets dict with only the extrated elements.

• The element indices of the new mesh are not the same as the former one.

• The new mesh keep the initial nodes and node_sets. To also removed the nodes, a simple solution is to use the method “remove_isolated_nodes” with the new mesh.
