My grandpa was an engineer who used AutoLISP a lot to automate away a ton of work they were having to do back in the 80s and early 90s, his coworkers loved him because he got menial things done easier for everyone. I could only imagine tasks like what they were doing involving complex fluid mechanics to be something you'd have to have a programming environment to get at.
