porespy.beta.fibers_2D

porespy.beta.fibers_2D(shape, r, n=None, porosity=None)

Generates randomly located fibers which are randomly oriented in the x-y plane but aligned in the z-plane

Parameters:

• shape (list) – The shape of the image to generate. This must be 3D.

• r (int) – The radius of the fibers to generate

• porosity (float) – The radius of the fibers

Returns:

im – An ndarray of the given shape with fibers indicated by False and void by True.

Return type:

ndarray

Notes

Drawing randomly oriented fibers with a uniform density is a surprizingly tricky task. The problem was recently discussed and a solution proposed by Beckman et al [1].
