I just recently graduated with my BS degrees in physics and applied math but am interested in switching my career path towards mechanical engineering. I honestly don't know much about CFD at all, so I was wondering how much of the fluid mechanics you learn in the ME classes is actually used in CFD for the graduate-level courses, and for actual engineers who use CFD on their job. I've taken one quarter of fluid mechanics in the ME dept and I enjoyed the entire course (we skipped the section covering Navier-Stokes, vorticity, etc) until the very end when we covered shock waves, sonic/subsonic/supersonic flows, isentropic flows, etc. But since I enjoyed mechanics, statics, and numerical analysis/modeling/simulation instead of experimental work, I heard that computational mechanics and CFD were good fits for me. Also, I want to apply my knowledge to work with tanks, missiles, and weapons systems. Since I didn't like the part of my fluid mech class that covered shock waves, does that mean I won't like doing CFD? how much of that is used in CFD? also, one last question I have is just a general question about ME: If I want to find a position in industry doing modeling/simulation work instead of experimental and hands-on work, do I need to do the thesis-option for my MSME? or can I find such positions with just the coursework-only MSME?
