I named surface in Ansys modeler as Inlet.

When i imported in to Fluent it is showing as multiple input bodies.

Kindly help.

one inlet face for each solid zone which you have

by the way, most likely you don't want contacts in your simulation.
in design modeler put all solids into one part, in mesher delete all contacts

Thank you.. It works....

But Its mean we should not divide the inlet or outlet components to multiple bodies.

Each zone is a distinct continuum and allowed to have its own physics. For example, one body could be a solid, one a fluid, one empty, a different solid, a diffferent fluid, etc. Each zone can have vastly different physics configurations and the types of boundary conditions that you give to boundary surfaces for these zones can be wildly different and even unique.

Each boundary surface logically therefore is paired only with only one cell zone, unless it is an interface between two zones.


If you choose to build your case using multiple bodies even though you intend to have the same physics declared in all of them, then you will end up with disjoint surfaces and cell zones and have additional interfaces. It's not wrong, it's just more number of parts you have to deal with. Just a bookkeeping problem.
