Videos from my CFD course in Boston University. Screencasts recorded live while lecturing in class, annotating on slides using a Wacom graphic tablet. Note: the original videos were uploaded to the Boston University YouTube channel in 2012. After more than 10 years, and having amassed more than a million views, collectively, I requested that the university take them down from their channel, and I re-uploaded them to my own channel. (I kicked myself over the years for not having used my own channel from the start!) The university set the videos as hidden, but did not delete them. (That is why you see a note here about hidden videos: they are duplicates.)
