[Gmsh] How and why to use tetrahedric or hexahedric elements ?

[Adrien Girard]

Hi everybody,

I have to mesh compresseur to do a modal analysis and a centrifugal one, and
I would like to have some information to do this :

- Which elements are better in my case and why ? Tetrahedrics or Hexahedrics
?
- I think I will use a quadratic mesh because I think its better, but why it
is ?

Thank you very much for your help. I am interested in any document you could
suggest me.
Best regards,


Adrien
