Coupling Algorithms for Partitioned Multi-Physics Simulations

چکیده
Partitioned coupling approaches are an important tool in order to achieve a decent time-to-solution for multi-physics problems with more than two physical fields or changing combinations of fields. We study different approaches to deduce coupling schemes for partitioned multi-physics scenarios, by means of a simple, but yet challenging fluid-structure-fluid model problem. To our knowledge, this is the first time that a fully implicit black-box coupling scheme for partitioned multi-physics scenarios is described. This allows the simulation of a new range of applications in a partitioned way.

A 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 کاملRobust Quasi-Newton Methods for Partitioned Fluid-Structure Simulations
In recent years, quasi-Newton schemes have proven to be a robust and efficient way for the coupling of partitioned multi-physics simulations in particular for fluid-structure interaction. The focus of this work is put on the coupling of partitioned fluid-structure interaction, where minimal interface requirements are assumed for the respective field solvers, thus treated as black box solvers. T...
متن کاملAnalysis of Long Time Stability and Errors of Two Partitioned Methods for Uncoupling Evolutionary Groundwater-Surface Water Flows
The most effective simulations of the multi-physics coupling of groundwater to surface water must involve employing the best groundwater codes and the best surface water codes. Partitioned methods, which solve the coupled problem by successively solving the sub-physics problems, have recently been studied for the Stokes-Darcy coupling with convergence established over bounded time intervals (wi...
متن کاملPreCICE – A Parallel und Efficient Coupling Library for Partitioned Multi-Physics Simulations
Flexible and extensible partitioned multi-physics simulation environments require efficient and modular tools with a broad and customizable coupling functionality. PreCICE [1] is a library for flexible numerical coupling of single-physics solvers. It uses a partitioned black-box coupling approach, thus requiring only minimal modifications to existing solvers. This fact and a clean API foster qu...
متن کاملFluid-Structure Interaction in the Cardiovascular System. Numerical Analysis and Simulation. (Interaction Fluide-Structure dans le Système Cardiovasculaire. Analyse Numérique et Simulation)
In this thesis we focus on the numerical analysis and the development of e cient partitioned algorithms for uid-structure interaction (FSI) problems arising in hemodynamics. In particular we consider the mechanical interaction of the blood with the large arteries, with the cardiac valves and with the myocardium. In partitioned FSI procedures the coupling between the uid and the structure can be...
