Hello Mahzad,
Defining the fiber reference direction (0o fiber direction) can be done easily with ACP (Ansys Composite PrepPost) and edge-wise rosettes (coordinate system):
The fiber orientation for elements inside the geometry will follow the edge-wise rosette as well. You can plot fiber reference geometry to double check the orientation for all elements.
There is a course on ACP on the Ansys Innovation Space (AIS):

Do you have access to the Ansys Learning Hub (ALH)? If so, there are courses on how to use ACP:

Let me know how it goes.
Reno.
