Fibers orientation

Coreform Cubit Geometry
#1

Is it possible to create different orientations of fiber in cubit?

#2

Hi @Nikhil231998,

Cubit does not have built in capability to support orthotropic materials. As a material model no.

I have seen people create geometric sections corresponding to a fiber angle and assign properties to a block defined by each geometric section. Doing that is a significant project.

Thanks,
Karl

For changing the fiber orientation, changing orientation of mesh will work?

Here is what I have seen before. The user was creating a test coupon. You can then assign angles to the element sets (blocks) in your analysis code. I don’t know if that captures your use case.
