FSI thin elastic flap error!!
 

Dear All

I am trying to setup FSI case by coupling Fluent with structural solver using system coupling in workbench, my domain is a rectangular duct where there is inside a cantilever beam, however whenever i assign a low thickness for the cantilever beam for example 0.03 mm, the data transfer in system coupling are not mapped, i get 0 percent area mapping, anyone know how to resolve this? this only occurs when i put low thickness, in large thickness, it works fine....
