Hi, I want to create different inlet velocities for the same fluid. For example, if i have a water flow entering a pipe, I want to change the velocity of the water in different inlet zones as rings shapes, the exterior ring with u=1 m/s and the interior ring u=0.5 m/s. Does anyone know how could this be simulated in the same fluid domain (pipe) or i should devide the fluid domain in zones? And how can I do it?

You can use profiles or expressions, but you may find it easier to split the boundary. Depends on what you're trying to replicate.

Thanks Rob, but i'm trying to split the boundary with regions and I don't even know how to make this regions, it has to be with ansys fluent meshing or in the setup phase? And how could I define a new veocity inlet in this region only aprt from the velocity inlet outside the region? Or maybe I'm wrong and I have to split boundaries in another way. Thanks.

I can't remember what Regions does! If you create a Register (under Adaption) then split by Mark. Note, as you're trying to split a mesh you'll not get a perfect shape as only cells entirely in the Register will be added to the new (or kept by the old) surface.
For precise splits use the Geometry tool(s), the surface splits in Fluent are to help with errors or where less precision is needed.
