Jacobian-Free Newton-Krylov with a globalization method for solving groundwater flow models of multi-layer aquifer systems

Raghav Singhal, Emin Can Dogrul, Zhaojun Bai

A Jacobian free Newton Krylov (JFNK) method with a globalization scheme is introduced to solve large and complex nonlinear systems of equations that arise in groundwater flow model…
