I need help with my external ballistic project

Hello! I'm doing my master's degree, and for one of my courses I'm working on a project in external ballistics. My task is to generate a Cd vs. Mach curve for a rocket and compare it with experimental data.

However, it has been a nightmare! I can't generate a good mesh. I've been trying to reduce the Y+ values on the rocket walls, but nothing seems to work. Inflation isn't helping, face sizing doesn't seem to make any difference, and my latest attempt was to split the face around the rocket wall so I could apply a different face sizing there, but that didn't work either.

I really need some help. This project is very important to me!
