nodal_difference_fc#
Autogenerated DPF operator classes.
- class ansys.dpf.core.operators.averaging.nodal_difference_fc.nodal_difference_fc(fields_container=None, mesh=None, scoping=None, config=None, server=None)#
Transforms Elemental Nodal fields into Nodal fields. Each nodal value is the maximum difference between the unaveraged computed result for all elements that share this particular node. The result is computed on a given node scoping. If the input fields are mixed shell/solid, then the fields are split by element shape and the output fields container has an elshape label.
- Parameters:
fields_container (FieldsContainer) –
mesh (MeshedRegion or MeshesContainer, optional) – The mesh region in this pin is used to perform the averaging. it is used if there is no fields support.
scoping (Scoping or ScopingsContainer, optional) – Average only on these nodes. if it is a scoping container, the label must correspond to the one of the fields containers.
- Returns:
fields_container
- Return type:
