Hi yanger11,
Did you create the CSYS (choose CYLINDRICAL)? After you create it, you choose MATERIAL ORIENTATION in TOOL-->you will be asked to choose the PART you want to assign the MATERIAL-->choose the CSYS you created before. That's all.
Hi brep and Bigtree,
I'm now working with 2D composite plate by ABAQUS CAE V6.6(the same case to brep). But the problem is to define the directions of the layers. Could you help me to figure it out?
