How to refine mesh?
 

I'm currently working on simulating a metal injection proces. I have managed to mesh my part with netgen. My problem is that netgen keeps crashing when I try to refine my mesh. Does anybody know why this happens? :confused:

Se the mesh here:

Furthermore I have had lots of troubles trying to install netgen 4.9 on Ubuntu. I haven't succeded yet, so if anybody has any good tips it would be welcome!
