Hello guys, I'm working on a REU project right now, and my job is to try to design a better vacuum system. being a noob at any aspect of mechanical engineering and designing (I'm a physics major, I know the physics but I am not familiar with how mechanical engineer does/designs things)... I need to find a software that does stress test on a given structure of given dimension and shape... I have no clue on what I should use. (it is part of my job to find that software....) If you guys can recommend some stress testing software, it'll be greatly appreciated.
