In [[multiphysics]] systems — systemssystems—systems involving multiple physical fields that interact with one another — linearizationanother—linearization with respect to each of the physical fields may be performed. This linearization of the system with respect to each of the fields results in a linearized monolithic equation system that can be solved using monolithic iterative solution procedures such as the [[Newton-Raphson]] method. Examples of this include [[MRI scanner]] systems which results in a system of electromagnetic, mechanical and acoustic fields.<ref>S. Bagwell, P.D. Ledger, A.J. Gil, M. Mallett, M.
