<DIV>I want to add a smooth method in the GMRES routine. I do it in the function KSPSolve_GMRES of /src/ksp/ksp/impls/gmres/gmres.c. The code likes that:</DIV>
<DIV> </DIV>
<DIV>PetscErrorCode KSPSolve_GMRES(KSP ksp) {</DIV>
<DIV>.....</DIV>
<DIV> ierr = GMREScycle(&its,ksp);CHKERRQ(ierr);</DIV>
<DIV> </DIV>
<DIV> ierr = MatRelax(ksp->pc->mat, ksp->vec_rhs,1,SOR_FORWARD_SWEEP,0,1,1,ksp->vec_sol);CHKERRQ(ierr);</DIV>
<DIV>.....</DIV>
<DIV>}</DIV>
<DIV> </DIV>
<DIV>But compile fail. Is it the right way? </DIV>
<DIV>Thanks.</DIV>
