That is typically tetrahedral meshing. Hex meshing is sometimes an option, with the caveat that the user must first decompose the geometry (slice it up) into simpler sections that are mappable. This seems to be automated polyhedral meshing. Which is interesting, but I imagine has limited applicability as most finite element software (that I'm aware of) relies on tet/hex element formulations. Maybe with this advance in meshing that will change, though.
