A monolithic approach to fluid-structure interaction

This paper compares partitioned and monolithic solution procedures for the numerical simulation of fluid–structure interactions. Their different stability properties are illustrated and the role of structural prediction for a partitioned method is discussed. A grid refinement study has been carried out to assess the temporal accuracy of these methods. Moreover, their computational cost as well as their computational efficiency is compared. Numerical experiments are presented for a one-dimensional model problem of a piston interacting with a fluid
