Linear system solver
 
Hallo!

Does anybody know what solver (for the linear system), Fluent use?? For example, does fluent include methods like GMRES, or BiCGSTAB. Can i choose??? And another thing. What is the stopping criteria (for the linear system solver)?? Is the relative residual: |A*x-b| < tol*norm(b) ???

and what is the value of tol? Can i change it?

Thanks for advanced!
