doing external flow with fluent , we supress geometry

so what is difference between making geometry region dead and solid ?

    It depends. If you don't want heat transfer through the solid part then dead is fine.

    You would need to map surface data to Mech and re-calculate the temperature field. If you want a temperature field in the metal bit(s) use Solid.

    Correct. Dead is void (effectively) where as solid is meshed and part of the model & solution.

    For info, "dead" was originally the designation for non-fluid cells when we had full cartesian meshes and needed to fit the geometry into a cuboid (last needed in Fluent 4). Those cells were included in the cell count, but didn't use much RAM. The term was retained for voids in Fluent Meshing.
