Hi people; I don't write much in the forums but i always read the threads time to time. I'm an astronautics engineer and studying in graduate degree on Advanced Technologies Aeronautics and Astronautics program in Istanbul Technical University. My thesis will be similar as my undergraduate thesis. Migration of the bubbles. I finished my first year and when i called my adviser to talk about starting my thesis, he said he quit the school and started to work in an airlines company. Worst of all, there are no teacher who works about my subject in my university. Probably, I have to start over on a new subject. I haven't done much things about my thesis except running 5 simulations (which lasts over 30 days for each simulation), but i was familiar to the subject and im not familiar about other subject. Adaptation on a new subject will be difficult i guess. Anyway thanks for reading.
