recheck for design of piles

i have gone through the model and the comments are as follows

1. 'Medium Dense clayey sand' 1 mesh set wasn't activated in the insitu stage. Also interface element along with rigid link has been created, so we need to activate the rigid link (Mesh Set Link) in the insitu stage and activate the interface element (Mesh Set) in the foundation stage.

2. We can't directly apply the moments on the plane strain elements. But one can directly apply the moments on 1D beam/truss element. So please apply the moments in the form of couple forces acting with some lever arm. 

Thanks & Regards,

Harsha
