reduce size of your mesh by using size function for instance.
Pictures may help

Measure size of geometry on different parts and apply size function accordingly.
For example is edge length is 10 then size of 1 would produce 10 or so elements. There apply sizing function with size 1, growth rate 1.1 to 1.2 and maximum size to 10 or as required. |

And split your volume into different volumes so to not have out of memory error message; obviously mesh one volume a time.
