By hand?  

In college (Aerospace Engineering in the early '70s) I wrote Finite Element
software to analyze trusses as my senior project. Still have the box of
computer cards somewhere (when was the last time you saw a card reader?). 

First job out of college was writing Finite Element software to analyze
nuclear reactors for Trident submarines.  Now that is a scary thought...

Oh yea, I still have a slide rule (and mostly remember how to use it)...
