Ajay,
IMHO, modeling complex curved geometries with hexahedral elements is an
extremely difficult problem. It can be done, but requires a lot of
manual manipulation. I have done it by generating meshes manually,
however these meshes are not fully parametric, which is a big drawback
because it makes them difficult to modify (or "remesh"). I recommend the
program TrueGrid (www.truegrid.com). It is relatively inexpensive, and
employs an interesting and powerful technique for generating parametric
hex meshes. They use a "seed and warp" approach that theoretically can
handle any geometry. It takes a while to figure out, but once you have
it... it's really great.
good luck,
