Hello Ahmed,nit's hard to speculate what goes wrong by only looking at the pictures. Have you used CONTACT_AUTOMATIC_SURFACE_TO_SURFACE with SOFT=1? SOFT=1 is generally more effective than SOFT=0 when soft materials come in contact with stiff materials or when the densities of the two contacting materials are dissimilar. Also check if the thickness of shells is reasonable. I suggest you start from a simpler model to first make sure that the contact works as expected. I hope this helps.nRegards,nak n
