  Hello,
  I encountered the following warning and would like to resolve it:
  *** Warning 50186 (MPP+186)
  segment contains rigid body nodes
  tracked node ID = 40242
  tied interface # = 10
  segment nodes:
  56438 56522 56523 56439
  
  In fact, I used the Tie-Node-Surface-Constraint_Offset card to tie a solid element to a rigid body.

  Hi
  Perhaps make sure that there is no overlap in meshes and use segment sets (say surfB is rigid only segment set only, and surfA is flexible only segment set).
  If you open the results and the parts are bonded and held/connected together then it should be ok - the check is most important.
  All the best
