Dear, A book with title "Finite to infinite" is good one. Another is FEA by P Sheshu..

Vivek Arora

who is the writer of finite to infinite? is it availabe online?

Pooyan Nikeghbali

I think for beginners "The Finite Element Method, zienkiewics,1979" is good and the FEM use in fluids I suggest "Finite Element Methods for Flow Problems, J. Donea and A. Huerta, 2003"
