  Dear Sir/Madam
  
  My question is, how can I make sure that thew core is correctly connected to the face sheets? For 22 bodies I get 14711 Nodes and 16388 Elements but when I opt to use contacts I cant really figure it out.
  
  Additionally I want to add a layer of Epoxy resin between the core and the faces. Should I just design an extremely thin sheet body and just appoint through material selection the Epoxy resin ? Or in the analysis settings should I just choose the surface coating method ?
  
  I know that because of the high modulus of elasticity I can avoid it but I will be doing a thermal stress analysis with a thermal cycle of -+ 120 degrees C so I want to check how it will operate and affect my model.
  
  And this is the connections:
  
  Please let me know if anyone knows what I should look for exactly.
  
  Kindly,
  
  Michael

  1. You can use bonded contacts between edges of the honeycomb structure and face sheets or you can keep them in a multibody part and use shared topology like you have used for the "part" in the geometry without using any contact

  2. I think you can use layered section as mentioned in the link above here.
