You can HEX mesh most of the part easily, but for the rest you need to have experience preparing the geometry. To start with please study & practice the following tutorial:

Thanks for your reply and for the exercise file,.... I don't have any problem with generating Tet. mesh but whatever I tried, couldn't created the Hex,... I'll follow the instruction as described in the file and will let you known if I have any problem.
Depending on what SOL you intend to run - you might find it easier/quicker to use some glue connections.
I had a quick look at the geometry this morning - my first initial thought was you will experience difficulty (not impossible) to mesh match the HEX as the plate has different thickness throughout - splitting those will require significant time.
The image below took me around 5 minutes - simply remove all rads etc, split the geometry into "common" sections, glue this together and run a free free modes to ensure connectivity. This will also work with including the rads etc just glue them also (increased connection regions).
This is not the perfect/only solution but it will save you a lot of time and effort trying to split every body to match.
There are quite a few tutorials available on glued connections, but below is how to achieve it in the most basic sense.
- Split your geometry into "hexable" solids (image shown is not), and decide where the hex transitions will be difficult to achieve.
- Make these surfaces your Glue contact surface
- Create connection property as shown
- Set up connector
In the previous post I had split the solid into quite a few individual solids which could be slaved to create three separate hex regions and glued these together using the above method.
