POLYFLOW - Warning received from ANSYS Polydata: "The domain of the sub-task is composed of disconnected sub-domains. Sub-tasks must be defined on connected sud-domains!" What can be done?

If the finite element mesh was not purposely created with disconnected domains, than the probable cause is an error in the mesh generation. This should then be checked in the geometry of into the mesher. In particular, it should be checked that parts are properly connected with each other.

If the finite element mesh was purposely created with disconnected sub-domains, then additional information can be found e.g. in section 8.19 (Non-conformal boundaries) of the ANSYS Polyflow manual.
