Sub modeling capacity in Fluent?

      In a huge model, some component/part can be replaced to save run time. For this you need to design your modeling system in such a way that it is modular. Let's say there is a portion of the fluid model (around a component or sub-system) that you want to replace in the future with a different version. You need to keep this region as a separate cell zone in Fluent. The boundaries of this cell zone will interface with the rest of the fluid domain using interior boundaries or walls or interfaces. Now, if you want to replace this cell zone, you can go to Zones > Delete (under 'Setting Up Domain' tab) and then delete this cell zone. Then go to Zones > Append > Append Case File and read the mesh corresponding to the new version of the component or sub-system. Now the new cell zone is inserted into the domain. Now you can use Combine > Fuse to fuse the face zones at the boundaries of this new cell zone so that it is integrated within the larger domain for conformal mesh. This case is now ready to be re-run.

      Do we have sub modeling capacity in Fluent? Details: Suppose I simulated a huge model; later on, one part or component or sub-system is revised or added. Can I replace the old component with new?
