Coupling schemes for the FSI forward prediction challenge: Comparative study and validation

Int J Numer Method Biomed Eng. 2017 Apr;33(4). doi: 10.1002/cnm.2813. Epub 2016 Jul 21.

Abstract

This paper presents a numerical study in which several partitioned solution procedures for incompressible fluid-structure interaction are compared and validated against the results of an experimental fluid-structure interaction benchmark. The numerical methods discussed cover the three main families of coupling schemes: strongly coupled, semi-implicit, and loosely coupled. Very good agreement is observed between the numerical and experimental results. The comparisons confirm that strong coupling can be efficiently avoided, via semi-implicit and loosely coupled schemes, without compromising stability and accuracy.
