I want to connect tet meshed bodies together using glue elements for modal and static analysis. Can the free face of the elements in each region be use for the connection or only entire elements?

  • oops, pretty old, but the right version for the "new" contact definition in Nastran. Check in the 2013.1 release guide the chapter "Contact User Interface Improvements (2013.1)"
     
    This is an extract of a 3 solid tetmesh example that should work in 2013.1. Btw, "bctable1,0" is required to get the initial contact status as result case.
