TITLE: How to use FEM to solve a PDE
QUESTION [5 upvotes]: I come from a Computer Science background and I've been around searching for a concise tutorial that tells me how Finite Element Method is used to solve a certain partial differential equation. Unfortunately I was depressed with the large number of advanced studies and papers that assumed prior knowledge. 
Is it possible to understand the entire process of implementing FEM easily?

REPLY [4 votes]: After a lot of search, I found this excellent crash course:
