How to declare PCOMPP card to Nastran solver

Hi, I,ve been trying to declare PCOMPP properties to my 2D composite model for Nastran solver as I used to do it for the Optistruct one. I've made all the laminates, plies and MAT8 materials but at the end, after exporting solver deck, PCOMPP, laminates and even plies do not appear in the BDF file.

I can't even choose the Card image for laminates and plies.

Is it possible to model composites with PCOMPP card for Nastran? or do I have to use PCOMP or PCOMPG and declare plies again?

    PCOMPP is exclusive for OptiStruct and Radioss solvers.

     

    But you can realize your laminate data, converting it to PCOMG, which is Nastran compatible. (at least in the OptiStruct user profile).

    Ok, I didn't know that I have to realize the laminates. Yup, now it's working.
    Thanks a lot.
