Check out the recent release of our
Incompressible Flow & Iterative Solver Software (IFISS)
package.
This is an open-source software package associated with the book
Finite Elements and Fast Iterative Solvers with applications in incompressible fluid dynamics
You can check out the contents from here using Google books.
The book provides an introduction to finite elements, iterative linear solvers and scientific computing aimed at graduates in engineering, numerical analysis, applied mathematics and interdisciplinary scientific computing.
The technically demanding theoretical aspects are largely confined to the sections on the 'Theory of errors'. Readers who would like a more gentle introduction to the mathematics underlying finite element convergence theory will find it useful to assimilate the material in our Finite Element Primer before reading the first chapter.
