I completed my undergrad in physics and applied math, and did 2 different research projects. I ultimately want to do modeling/computational work (since i would much rather do numerical analysis than experimental work) for an aerospace company/defense contractor doing work related to making weapons, tanks, and missiles. This past week, I got accepted by my current school's MAE department for the MS program. For now and the spring quarter, I was thinking of just continuing to apply for internships or full-time engineering positions, and if i can't get one by the MS admission deadline, i'll accept the MS offer. Now here's the problem. If I do the MS, I wish to do the thesis option, since I can get funded for it if I find a research advisor. However, I'm not sure what area I'd like to do research in. Since i've only taken 2 engineering classes, intro to fluid mechanics and intro to heat transfer, I'm debating between CFD vs heat transfer vs structual analysis. CFD seems to have the most applications related to analyzing aircraft and missiles, which is what I wish the most to do. In my heat transfer class, I enjoy the concepts we're learning, but I don't like how all the applications seem related to pipes, heat exchangers, etc - nothing related to aircraft and missiles. Structural analysis seems to draw from statics and dynamics, which according to the textbook I skimmed through, seemed to focus on designing stuff like buildings and bridges. But from my lower-div physics mechanics course, I enjoyed statics and dynamics the most Any ideas of how to narrow down my research interests? Or maybe I'm better off just doing the non-thesis option, since I like studying ME in general, even though I have to pay for it?
