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

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.
