Here is an image of the model. The seen are restrained in ux,uy, and the first node of the row in ux,uy,uz (only one node is restrained in all three degrees of freedom). The whole structure is meshed witth an element size 0.5 ( esize=0.5). The load is applied in a form of a displacement( seen in the second picture) firstly the nodes are given a displacement equal to 10mm in the uy direction(vertical) and then in the -ux equal to 0.5. this is done in order to simulate shear stress in the core.The model is connected with AOVLAP command. Hope this is enough for you.
