Fluent: Error when separating Fluid zone
When a fluid zone is separated using cells marked using a Boundary zone, Fluent reports following error:
Error: update_cell_references: not all faces on thread 10 share cell
Error Object: ()
This error occurs if there are Grid interfaces in the mesh file and the cells that are marked for separation cross the grid interfaces.
Work around to this problem is to delete the grid interfaces which are crossed by the marked cells, then separate the fluid zone using the Mark option and redefine the grid interfaces. The interfaces will also be split so new grid interfaces for these should also be created
