  • mesh_scoping (Scoping, optional) – Average only on these entities

  • should_average (bool, optional) – Each nodal value is divided by the number of elements linked to this node (default is true for discrete quantities).

  • extend_to_mid_nodes (bool, optional) – Compute mid nodes (when available) by averaging the neighbour primary nodes.

  • extend_weights_to_mid_nodes (bool, optional) – Extends weights to mid nodes (when available). default is false.

  • mesh (MeshedRegion, optional) –

Returns:

  • field (Field)

  • weight (PropertyField) – Provides the number of times it was found in the elemental nodal field, for each node. can be used to average later.
