PCPARMSSetSolveTolerances

Sets the convergence tolerance and the maximum iterations for the inner GMRES solver, when the Schur global preconditioner is used.

#include "petscpc.h" 
PetscErrorCode PCPARMSSetSolveTolerances(PC pc,PetscReal tol,PetscInt maxits)

Collective on PC

	pc	- the preconditioner context
	tol	- the convergence tolerance
	maxits	- the maximum number of iterations to use

	-pc_parms_solve_tol	- set the tolerance for local solve
	-pc_parms_max_it	- set the maximum number of inner iterations

See the pARMS functions parms_PCSetInnerEps and parms_PCSetInnerMaxits for more information.
