Meshing Complex Conical Geometry
 

Dear experts,

I would like to model heat transfer inside a solid geometry, consisted of four parts (as shown in the below link).

Each part has its unique physical properties. The curved surface is heated by convection, while the straight faces are considered as symmetry planes.

I do not have experience with ICEM CFD, which I think can handle this complexity. Do you have any suggestions how to mesh the geometry using the ANSYS meshing tool?

Any advice is very much appreciated!
