Error “element ID 13546 has a zero normal vector”

    • mmia1

      Could anyone please guide me how to solve this error "element ID 13546 has a zero normal vector"?

      I was trying to connect two straight pipes having same length. In the connection place, I was trying to create nodes having similar coordinates. For instance, the first pipe end nodes have same coordinates as the second pipe front nodes so that they can be merged by *NODE_MERGE_SET. But getting error as "element ID 13546 has a zero normal vector"

      Hi , can you able to check the ELFORMS and check the normal direction of your shell elements and make sure that they are all facing the same direction within a single part. 

      Cheers, Ram
