 June 18, 2006, 08:30 Re: preconditioner of a matrix #3 khaiching Guest   Posts: n/a a sparse matrix, typically arisen from the assembly of coefficient terms of the Pressure correction equation/others in incompressible CFD calculation.. I am trying to solve the entire matrix using the Preconditioned Conjugate Gradient Method.. However, I have no idea to construct the preconditioner.. Can you guys help me on this?? Thank you. -khai ching-

It is inexpensive (\$18/\$14.14 SIAM members) and would be a useful addition to any library. Ordering information at http://www.netlib.org/templates. The text is available for free at http://www.netlib.org/templates/Templates.html. There is a chapter on preconditioners. The book gives many algorithms (templates) from which you can code solvers and a few preconditioners in any language you want.
