ERROR 606

*** ERROR # 606 ***
Element 1 references a PCOMPP card without being referenced
by any STACK card.

Hi,

I'm a novice performing a buckling analysis on a hollow cylinder made of 10 layers of E-glass epoxy. I am encountering this error when i try to run the analysis on optistruct. I am working on hypermesh v11. Please tell me exactly how to rectify this error.

Thank you for your help,

Karthik

P.S. I have attached my file for reference

Hi @k@rthik

Please update the laminate and Plies with STACK and PLY cards, respectively and also there is a part component which is covering the mid-surface. Not sure what it is...

Thank you for your response. I updated the stack and ply cards but I am still getting the same error

There a component with shell elements (PART) which doesn't have plies. .I deleted that and here is the updated model.

Please re-apply the loads and spcs
