For a homogeneous material (no layers), for the single fiber type, use the data from an Estimate Fiber Diameter result file (*.gdr) obtained with FiberFind and, for Diameter, enter the value of the estimated Average inner diameter.

Alternatively, click the Diameter’s Edit… button and choose Gaussian (or Log-Normal) to enter the values of the Average inner diameter and the Standard deviation from the fiber diameter result file.

It is also possible to choose Probability Distribution and to enter a stepwise distribution, e.g. from the histogram values of the fiber diameter estimation.

Enter a Length that fits to the length of fibers in the structure (e.g. the length estimated during fiber identification (see Identify Fibers).

For the example shown above, with fibers having their start and end points beyond the domain, enter a Length that is larger than the largest side of the domain. For a domain of 200 µm x 200 µm x 200 µm used here, enter e.g. a length of 250 µm. Infinite circular fibers could be chosen as fiber type as well here. They already extend beyond the domain.

Using an Estimate Fiber Orientation file (*.gdr) obtained with FiberFind, click now the Orientation Edit… button to enter these computed values.

Now, under the Create Options tab of FiberGeo, enter the estimated Solid Volume Fraction as Object Solid Volume Percentage in the Stopping Criterion panel. There are no layers and, thus, the calculated SVF corresponds to the Object Solid Volume Percentage of the complete media.

Remember to set the correct domain size (NX, NY, NZ) and Voxel Length in the Domain panel (Create Options tab).

Click OK to close the FiberGeo Create Options dialog and click Generate in the FiberGeo section.

The reproduced fibrous material model appears in the Visualization area, matching the values estimated by FiberFind for the 3D material model obtained from importing (µ)CT images.
