material orientations along spline

[Minkowski]

hello everybody,

first, excuse for my english, i'm french

I'm a new user in Abaqus CAE, and I want to modelize short fibers orientation. I created groups and affected them different orientations, but it's too discontinued !!!

I want to know if it is possible to affect material orientations along a spline : fiber axes are colinear to the spline.

Abaqus CAE propose only material orientations along CSYS.

Any ideas ??

Thanks,
Thomas
