Fiber Orientation During Deformation

As from what I know, Fiber orientation will undergo changes during deformation. For example, let's consider an isotropic hyperelastic material with fiber angle, A=60deg from horizontal (positive x-direction). When we apply positive x-directional force on the sample, with the other end fixed, the material will deform, the fiber orientation will also undergo changes (perhaps less than 60deg now).
So when I do this in COMSOL, I define A=60deg separately, then I define I4 (solid Mechanics) in terms of A. My question is that, in this case, under deformation, COMSOL will automatically adjust the fiber orientation as real case, or constantly 60deg?
If constantly 60deg, got any idea how to do it like orientated themselves?
Thanks
