Partitioned simulation of fluid-structure interaction

چکیده
Simulations of fluid-structure interaction (FSI) are increasingly being used to calculate the mutual interaction between a fluid flow and a flexible structure. Mature, reliable and optimized codes are readily available to solve flow equations or structural equations separately but the handful of monolithic codes which are able to solve all equations in an FSI problem simultaneously have not yet reached this level of achievement. These monolithic codes are hard to manage and develop due to their vast size and complexity. Moreover, they cannot benefit from the fast solution techniques that have been developed for either flow equations or structural equations but they must settle for a compromise. Consequently, there is a strong need for partitioned solution techniques to couple an existing flow code with an existing structural code in a stable and efficient way.

متن کاملA coupling environment for partitioned multiphysics simulations applied to fluid-structure interaction scenarios
An efficient way to simulate multi-physics scenarios is given by the partitioned coupling approach. It allows to take up established simulation codes for single fields and combine them to one multi-physics simulation tool. The challenges appearing there range from purely technical, such as data communication, via numerical, such as data mapping and transient coupling algorithms, to software eng...
متن کاملSimulation of fluid-structure interaction with the interface artificial compressibility method
Partitioned fluid-structure interaction simulations of the arterial system are difficult due to the incompressibility of the fluid and the shape of the domain. The interface artificial compressibility method (IAC) mitigates the incompressibility constraint by adding a source term to the continuity equation in the fluid domain adjacent to the fluid-structure interface. This source term imitates ...
متن کاملPerformance of a new partitioned procedure versus a monolithic procedure in fluid–structure interaction
Fluid–structure interaction (FSI) can be simulated in a monolithic way by solving the flow and structural equations simultaneously and in a partitioned way with separate solvers for the flow equations and the structural equations. A partitioned quasi-Newton technique which solves the coupled problem through nonlinear equations corresponding to the interface position is presented and its perform...
