Shape-on-shape smoothing

Dear forum,

I am currently trying to create a hexahedral type mesh of a domain with a bullet shape inside it.
Is it possible to make a “Divided disk” take the form of the bullet nose? I attach a picture so you can better understand what I mean. I am quite new to Salome geometry+mesh and at the moment this is the best idea I have in order to create the hexahedral mesh on the rounded geometry. Any advices or tips are welcome.

Best regards,
