Coarse level Newton-Krylov acceleration of sub-iterations in partitioned fluid-structure interaction

Computational fluid-structure interaction is commonly performed using a partitioned approach. For strongly coupled problems sub-iterations are required, increasing computational time as flow and structure have to be resolved multiple times every time step. Reductions in computing times can be achieved by e.g. improving the convergence of the sub...

Fluid-structure interaction simulations: Efficient higher order time integration of partitioned systems

The simulation of fluid-structure interaction can be a very time-consuming task due to the large amount of time steps that need to be taken in order to obtain an accurate solution. To reduce computing times a higher order time integration algorithm is applied. Based on a mixed combination of implicit and explicit multistage Runge-Kutta schemes,...
