RE: FEA VS Textbook
That said, you should always do at least a "sanity check" calculation on your FEA just to filter out any BC or load errors and to feel confident that you believe the results.
Think of it as hand tools vs. power tools. There is a lot of overlap between when each can be used but, sometimes you need to fine control and feedback of a hand tool and other times you need the brute force and speed of the power tool.
You don't hang picture frames with a nailgun and you don't go through a 4x8 sheet of plywood with a hand saw.
