Hello forum,
i have generated a triangular shell mesh for a surface. After the output as a LS-Dyna key-file, i noticed that there are 4 nodes per element. How can that be? Triangular elements should have only 3 nodes? I got an output like this: *ELEMENT_SHELL $# eid pid nid1 nid2 nid3 nid4 1 1 23 21 24 24 ... So the nid4 is just the nid3. What am i doing wrong? Has someone a clue and would help me? Best regards. |

Collapsed cons? Check the geometry once again.
Second order element should have 6 nodes. So this is not second order element. Let us know once you solve this.  Quote:
