The materials are transversely isotropic in local coordinate systems along the length as you can see in the picture, the material change by the angle of each line inside of geometry. but I use a rotation matrix to calculate the material properties in a global coordinate system. But I don't know how can apply these random material properties. Should I use Matlab code or name selection in Ansys? Can I use an automatically named selection? because manually take a lot of time
