Are the coefficients constant in space? If so, you might try FFT´s, which provide a direct method (see Numerical Recipes Chap. 19). If not, Stuart Norris has implemented a number of iterative and direct solvers in SixPack (available at http://www.esc.auckland.ac.nz/People/Staff/Norris/).

Regards,

Francisco.

Assalam Alaykum wa Rahmatullah Dear Sir I am doing M.E. by research in NED University my research project is "revemping of Francis Turbine applying CFD".I am studying solution of different equations like laplacian equation,poission equation,but still i haven't got any book or research paper in which solution of Navier-Stoke equation and Euler equation is present.If you know any book or article which will be helpful for me please informe me. waiting for ur prompt reply Wasalam, MUKKARUM HUSSAIN RESEARCH ASSISTANT
