fedoo.Mesh.find_elements

Mesh.find_elements(selection_criterion: str, value: float = 0, tol: float = 1e-06, select_by: str = 'centers', all_nodes: bool = True)

Return a list of elements from a given selection criterion

Parameters:

• selection_criterion (str) – selection criterion used to select the returned elements. See fedoo.Mesh.find_nodes() for available criterion.

• value (scalar or list of scalar of numpy array) – value used for the selection criterion. See fedoo.Mesh.find_nodes() for details.

• tol (float) – Tolerance of the given criterion. Ignored if selection_criterion is an arbitrary expression

• select_by (str in {'centers', 'nodes'}, default = 'centers') –

  • if ‘centers’(default), the element is selected if its center verify the criterion.

  • if ‘nodes’, the element is selected if one node or all its nodes verify the criterion. depending of all_nodes.

• all_nodes (bool, default = True) – Only used if select_by == ‘nodes’. If True, get elements whose all nodes verify the criterion. If False, get elements that have at least 1 node verifying the criterion.

Return type:

List of element index
