need a solver for linear equation

hilllike · October 26, 2012, 05:06

Hi, gays!

I wrote a code based on multi-block grid, which generate a very special matrix.
Does anyone know some code to solve this problems? Any suggestion will be appreciated.
Thanks!

Try PETSc (http://www.mcs.anl.gov/petsc/). It has many different solvers for sparse matrix systems.

Thanks.

I want to find some code that can cooperate with my own code.
The easier, the better.

Yep, PETSc will certainly work with any code. I am sure there are other options as well.
