Efficient numerical methods for partitioned fluid-structure interaction simulations

Fluid-structure interaction simulations are crucial for many engineering problems. For example, the blood flow around new heart valves or the deployment of airbags during a car crash are often modeled with fluidstructure interaction simulations. Also, to design safe parachutes, simulations are carried out to model the unsteady deformations of...

Multi-fidelity methods for fluid-structure interaction and uncertainty quantification

The cost and turnaround time of the load calculation cycle in the design process of aircraft can be reduced by developing new numerical simulation technologies aimed at efficient prediction of steady and unsteady force coefficients in the flight envelope. In order to capture the most extreme stress levels due to gust and manoeuvres, efficient...

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,...
