## Abstract The numerical solution of fluid–structure interactions with the customary subiteration method incurs numerous deficiencies. We propose a novel solution method based on the conjugation of subiteration with a Newton–Krylov method, and demonstrate its superiority and beneficial characteris
In an implicit Newton-Krylov method for inviscid, compressible fluid flow, the derivation of the analytic flux Jacobian can become quite complicated depending on the complexity of the numerical flux calculation. Practically, the derivation of the exact Jacobian by hand is an unrealistic option becau
