      GMRES is a new stabilization method in R19.2 which is Generalized Minimal Residual Method. It is used for improving convergence of the linear solver and providing stability for the algebraic multigrid (AMG) solver. GMRES is recommended when you cannot reach convergence with the bi-conjugate gradient stabilized method (BCGSTAB) For more information please check help manual.
