try mtl and itl: http://www.osl.iu.edu/research/mtl/ and http://www.osl.iu.edu/research/itl/ mtl is a library for dealing with sparse matrices and itl has krylov solvers based on mtl format.

I've been using these libraries for almost 6 months, and I'm pretty sattisfied with it. Feel free to ask any questions, but I suggest you to suscribe to their mailing list, because this way you'll get the answers from the code developpers.

Best regards,

::but can i use it in visual fortran.

I don't know if you can call mtl from FORTRAN, because it uses C++ data structures that are not part of FORTRAN, such as classes and templates. Maybe you should take a look at netlib (www.netlib.org). It has a lot of free scientific software, and most of it is written in FORTRAN.

::what subject are you study i mainly work in region of numerical simualtion of incompressible flow and heat transfer

I'm working with incompressible flows too, but without heat transfer. I'm studying a finite element formulation that provides mass conservation at a control volume level, known as CVFEM - control volume finite element method.

best regards

Dear ztdep,

Do check out the book on Numerical Recipes in Fortran(also available in C) for information on numerical codes concerning scientific computations.

Regards,

Ganesh
