    Hi,

     

    always review the out file for warnings and errors:

     

     *** ERROR # 772 ***
     It is invalid to use a free grid as an independent grid in RBE3 data.
     Free spiders are not allowed to be independent grids in RBE3 data.
                    RBE3 id =     5082
               free grid id =        2
        weighted components =      123
     You should remove this grid from the RBE3 data.

     

    Use Tools>model checker>Optistruct to find modeling errors & warnings and apply autocorrection. Or use Check Elems Panel (F10)>1D>free 1d nodes.

    Thank you.

     

    Others two questions:

    1- I want do simulate a bidirectional, how i simulate that? If i put E1 and E2 equal, means that it is bidirectional?

    2- I also want simulate the resin between the plys. I consider it is MAT1?

    Glad to help.


    1. Yes.
    2. In ply based modeling the resin and fiber material properties are usually homogenized on a ply level. Multiscale Designer can be used to model the composite behaviour at the constituent scale.
