I have a case with many different inlets. Massflow, turbulence, local coordinate system etc. are different for each inlet which makes it quite hard to set up. If I read a new mesh (with the same inlets defined) into FLUENT, unfortunately all the boundary information is gone and one has to go manually through all the inlets again. Is there a clever workaround for this inconvenience? I have fiddled with the ASCII case file copying and pasting mesh and case info, but that approach is not manageable.

create a journal file and keep it, then read the mesh , and read the journal to define the boundaries again. its easy to do.

I thing you can try to create a bc file by typing file/write-bc at the TUI. Then when you read the new cas (new mesh) if it has the same names by reading the bc file (files/read-bc) fluent will copy the boundary conditions of the zones that have the same name and will skip the new ones. Hope it helps
