I am doing analysis of a unique CFRP pipe by Optistruct.

I am receiving this following error message:

  *** ERROR # 605 ***
  Element 1 is referenced by STACK 1 (on PLY 1) and by
  STACK 2 (on PLY 5) simultaneously.



Different stacks are created by dividing the upper and lower areas of the pipe into sets.

There seems to be an error because it refers to the same element

Is there any good way to do it? (Modeling is possible but analysis is error)

Thank you for reply


I understand that I use the same elements, but I do not know the idea to fix this modeling.
I thought it was a good idea to create several Sets and apply the same elements ...


For the time being, laminate information does not use the same ply.CFRP-PIPE-Asymmetric laminated.hm 


Perhaps, can not you create a pipe like this?

So, As a result I would like to see the deformation of the central section. (Node data in CSV format)

As you probably would use Tracing, how is the central cross section seen?

I made a set list of nodes in advance, but it can not be specified in HyperView's Tracing.

I do not know whether it is Lines, but

I created a node set in advance on HyperMesh as shown in the figure.


The graph gets displacement, but I simply want to know the position of the node.
(Cross-sectional shape of deformation;  for example, the second image below)


Is there a nice way?


Thank you.
