Hi Nanda
The Bolt is only modelled very crudely as it's not the main focus of the simulation. the force is indirectly intoduced through a backingplate at the bottom side of the sandwich. I put a picture of the crosssection of the insertsystem at the bottom.
Face sheets are yellow, core is red, potting compound is blue, insert and U-shaped mount are grey and the backing plate is black/dark grey. The hole i the middle of the insert is not threaded and the force is introduced perpendicular to the faceshets.
