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.0
