Surface to Surface Contact, Mid-Surface Mesh

      Hi,

      What would be the ideal way to mesh a bonded joint between two structural components using mid surfaces? (ANSYS WB 2014)

      1. A gap with MPC elements and pinball radius (as shown) or

      2. No gap and connected structural components

      I believe the latter will increase mass and rigidity because of the mid surface mesh.

      Thank you!

      nnUse MPC contact for bonded as much as possible unless overconstraints exist. It is-n? Ideal for shell-solid, shell-shell, and beam-shell contactsn? Interface with small gap/penetrationn? It avoids spurious frequencies for modal analysisn? Rather than modify the geometry to fill the gap, they cannbe accurately ignored when using MPC Contact or a fixednjoint.nRegards,nAshish Khemkan
