Abstract: Continued growth in the complexity of computational models has resulted in an increased demand for solution methods for nonlinear problems with characteristics that challenge the commonly used Newton-Krylov method. Coupled multiphysics problems and material science applications often lead to problems for which Jacobians and Jacobian-vector products are not available. In addition, nonlinear equations which mix stochastic and deterministic approaches are becoming more common. These problems lead to random errors in the evaluation of the nonlinear residual which do not work well with Newton¡¯s method. The speakers in this mini-symposium will discuss recent work in development and application of nonlinear, iterative solvers to problems challenging traditional Newton-Krylov methods.
