How to create different kinds of meshes in different districts

How to create different kinds of meshes in different districts in different parts of the geometry? For examples, I want to create finer meshes in the inlet channel, but I do not need create such finer meshes in the main channel. Or some parts of the geometry needs boundary layer meshes, and some do not need. How can I do that? I should create these different parts as separated topological structures and not unite them as a whole unit? Who know this, please tell me something. Thank you so much.
