What does 71 min bake mean? I know baking means to cache the results of a simulation but how do we interpret the time measurement?
This slide comes from some YouTube video; the details in the caption are not particularly important for your understanding of the class! That being said, "71 min bake" probably means that it took them 71 minutes to compute all the frames of simulation, i.e., to compute the generalized coordinates at each moment in time. (But that's just a guess! I suppose it might have also taken them 71 minutes per frame...)
