Because Fluent does allow gradient mash for structure mashing, I split my structure into a few parts and crate gradient by myself (see image). The problem is that separating the part crate wall in my flow, and I cent reached the part, so what can I do?

In Fluent, you will need to create mesh interfaces between your different zones.

Go to Domain > Mesh > Interface and select the corresponding wall zones to create these interfaces. Fluent will then automatically set fluid-to-fluid boundaries as type interior.
