How to do hexamesh on imported geometry?

Hi all, 

 

I'm trying to mesh a geometry that is imported from a STEP file. I'm thinking about doing a hexamesh for the solids and just automesh for the surfaces. The thing is though, I have no idea how to map the geometry before I mesh it with hexamesh. Can anyone please help?

 

I'm attaching the .hm file with the geometry that I have.

 

Cheers,

    how important this is to be made by hexamesh? Meaning, what is your area of interest in this case?

    The connection is not so trivial, and i'm not sure how to make it mappeable too.

    depending on how important or not, i'd try to make it hybrid, hexa and tetra, or just tetra second order.

    Or maybe you could cut the solids in parts mappable and do hex mesh separately, and then glue them with Freeze contact.

    It all depends on what are you interested in, and what analysis are you performing.

     

    Maybe someone has a nice strategy for your part, but honestly, i would save some time on meshing, and lose some time on running the solver, depending on the analysis.

    Try to mesh following this procedure on similar geometry:
