- Parameters:
mesh (MeshedRegion) – Mesh with arbitrary element types.
- Returns:
mesh (MeshedRegion) – Tetrahedralized mesh.
node_mapping (Scoping) – Node mapping.
element_mapping (Scoping) – Element mapping.
Examples
>>> from ansys.dpf import core as dpf
>>> # Instantiate operator >>> op = dpf.operators.mesh.mesh_to_tetra()
>>> # Make input connections >>> my_mesh = dpf.MeshedRegion() >>> op.inputs.mesh.connect(my_mesh)
>>> # Instantiate operator and connect inputs in one line >>> op = dpf.operators.mesh.mesh_to_tetra( ... mesh=my_mesh, ... )

- Parameters:
server (server.DPFServer, optional) – Server with channel connected to the remote or local instance. When
None
, attempts to use the global server.

- Returns:
outputs
- Return type:
- property config#
Copy of the operator’s current configuration.
You can modify the copy of the configuration and then use
operator.config = new_config
or instantiate an operator with the new configuration as a parameter.For information on an operator’s options, see the documentation for that operator.
- Returns:
Copy of the operator’s current configuration.

Examples
Modify the copy of an operator’s configuration and set it as current config of the operator.
