The values of the orientation tensors and the calculated diameters can be entered in FiberGeo to generate a matching digital material model.

Start with the values estimated by FiberFind for the fibrous material: the average fiber diameter and the diameter distribution for the whole domain, as well as the fiber orientation tensors for each block. This diameter distribution and the per-block orientation tensors can now be entered in FiberGeo to reproduce the fibrous material.

Select Model → FiberGeo in the menu bar and click the Options’ Edit… button in the FiberGeo section.

In FiberGeo, go to the Fiber Options tab and begin entering as many fibers of type Short Circular or Infinite Circular as the number of blocks in which the domain has been subdivided. For a homogeneous material, this is a single fiber type. For a layered heterogeneous material, this is a fiber type per media layer. In FiberGeo, it is possible to use up to 8 different fiber types.

Later, all fibers can be assigned to the same Material ID.

Set the Percentages are as Volume % (bottom right) to be able to define the desired fraction of the total volume of the fibrous structure according to an Object Solid Volume Percentage (SVP) value. Please refer to the FiberGeo user guide for a more detailed description of the different FiberGeo Create Fibers options.
