I'm attempting to model flow through a pipe where an exterior cold source is chilling the fluid in the pipe.

I know I need to generate separate meshes for the pipe wall and the fluid. I've heard that I can cap the ends of my pipe with a surface body to generate the fluid domain, but I seem to be confusing myself trying to figure out how to do that.

Do I create the cap as a feature in the Design Modeler module? Searching through Ansys' help resources, it looks like a cap can be create within Fluent using Mesh Generation -> (create) caps... but Mesh Generation is greyed out for me in Fluent. I'm working from the Workbench to pass the project between the different modules, so I'm not sure if this option is greyed out because I already went through the meshing module?
