Hi,
I am a running a FSI simulation, Mesh is coalapsing after some iterations (Using two way coupling of FSI ),is it generaly happened in FSI simulations in small regions ( iam ruuning simulations of 30 mm gap bitween two walls of cylinder ). due to sloshing stucture is defroming in vessel .

(flow conditions are incompressble turbulent flow, material is PVC ,)

from experiments deflection of structure is 4 mm(four milli meters)
i am refering this paper:http://www.sciencedirect.com/science...e54ecf8001d2a3

Can you people give sugesstions for moving mesh and FSI simulations to overcome drawback of mesh coalapse
