To align the 0 degree plies with the loading direction, a local coordinate system needs to be defined and assigned to the elements.
To define a local, rectangular coordinate system with the x-axis aligned with the global loading direction (the global y-axis), enter the following into the command prompt: LOCAL,11,CART,0,0,0,90,0,0
To assign the local coordinate system to the elements, enter ESYS,11 into the command prompt. The image below shows the local coordinate system relative to the base of the part.
