Hello!
As a part of the student project I perform the composite optimization of the composite structure (fig.1- Composite structure).

I have a few questions:
1)When I specify interface surfaces according to books and manuals, there is an error (Fig.2-3,4) in displaying plies when modeling an external closed skin.
Is it?
- A display error and is there a possibility to compute correctly
- An error in which correct computation cannot be performed
- …..?
Is it necessary to change the strategy of CAE-modelling? Could you suggest any options to solve this problem?



Noticed Feature:
I choose the strategy of CAE-modelling (Fig. 5 - Element’s normal and sublaminates, fig.6-7 ply’s normal for sublaminates №2-3).



When I use 1 ply for sublaminates №4,5 then I have the display error (Fig. 8), but when I use 2 plies for sublaminates №2,3,4,5 or 3 plies (Fig. 9), or 2 plies for sublaminates №2,3 and 3 plies for sublaminates № 4,5 (Fig. 9) then display is correct (interfaces laminate is the same). If I compute with this display error, the results will be correct or not?


- Is it possible to set links for plies of different sublaminates when performing shuffle optimization? How can I do it?
For ex. The dependent i-Layer# of sublaminate #1 must be laid similarly to the leading j-layer of the sublaminate #2 (Fig.10)

3. There is the following error when assigning a Sublaminate to a dshuffle variable: fig.11-12. Is it possible to assign Sublaminate for a dshuffle variable?


I would be grateful for your help!
