Abstract
Problems in structural mechanics can be very large scale and also extremely ill-conditioned due to both a small mesh-size parameter and extreme values of the problem parameters. Their numerical solution require iterative solv ers with efficient preconditioners. In this paper preconditioners based on separate displacement orderings and mixed variable methods are considered.
