Jul 30, 2008 #6 truckcab Automotive Jul 28, 2008 58 0 0 SE Hi, put the elements in a set and use the *RIGID BODY utility, I don't exactly remember the syntax, but its very straight forward. Check the manuals. Upvote 0 Downvote

Jul 31, 2008 #7 truckcab Automotive Jul 28, 2008 58 0 0 SE Hi again this is how you should do: 1. Put all of the elements in one element set: *ELSET,ELSET=ORPHAN_MESH_TO_RIGID el1, el2, ...,eln etc. 2. Use the *RIGID BODY facility: *RIGID BODY, REF NODE=NNNN, ELSET=ORPHAN_MESH_TO_RIGID (NNNN is a reference node for the rigid body) And then you have yout rigid body. Upvote 0 Downvote
