This second edition has two parts. The first part is the complete
classic by Gilbert Strang and George Fix, first published in 1973. The
original book demonstrates the solid mathematical foundation of the
finite element idea, and the reasons for its success. The second part is
a new textbook by Strang. It provides examples, codes, and exercises to
connect the theory of the Finite Element Method directly to the
applications. The reader will learn how to assemble the stiffness matrix
K and solve the finite element equations KU=F. Discontinuous Galerkin
methods with a numerical flux function are now included. Strang's
approach is direct and focuses on learning finite elements by using
them.
