Lower and upper layer of shell element will be defined according to the normal of element.

Hi there,
I am modelling compostie materials with shell elements and I have noticed that if you display element stresses/strains (2D) you have the option to display midlpane or Z1 or Z2 results whereas when you display composite stresses/strains you do not have this option but you can only see (probably) the midplane result for each ply.
Do composite stresses do include only midlpane stress for each ply? How to consider bending stresses wich are present in the Z1 and Z2 layer?

Hi MSC,
Please refer to CSTRESS card on OptiStruct help.
You can manually edit the deck to introduce NDIV values to calculate stress values at planes.

Thank you, that would help me a lot. I am using the lastest version 13.0 but in the OptistrucHelp under CSTRESS I cannot find the information you have shown....there are just additional 10 comments for cstress...but your screenshot shows that NDIV is refered to in commet no. 11....I don't see that. In the control card of cstress I only have the options FORMAT,TYPE and OPTION. I work with ply-based modelling with PCOMPP cards.
I have tried to edit the .fem (I am using OptiStruct) file and updated the line to
CSTRESS(H3D,NDIV=2) = ALL
but nothing changes...I still get the results of the midplane only :-( How can I set this?
P.s: Optistruct Input Deck Generated by HyperMesh Version : 13.0.0.119

Can somebody provide me the complete page of the manual Prakash us showing in this thumbnail? I am using HW 13.0. but my documentation for CSTRESS ends with point 10...unfortunately Prakash is refering to point 11. I don't know how to introduce the NDVI option to the input deck (syntax, location within the code).
