After the calculations, a Result Viewer opens showing the calculated fiber orientation tensors and solid volume fraction for each block. The tensor describes the statistical distribution of orientation in that particular block.

With an undivided domain (1x1x1 blocks), only one tensor for the complete domain appears in the Result Viewer.

With the domain subdivided into 3x3x2 blocks, the number of tensors is 18.

A detailed description of the orientation tensor and its components is also given in the Orientation section of the FiberGeo user guide.

The components of the orientation tensor in X, Y and Z direction are shown for all three coordinate directions in the Results - Plots subtab.

The fiber orientation in the blocks can be visualized by clicking Load .stl to get the 3D Orientation Arrows under the Fiber Orientation Visualization tab.

The fibers of the structure obscure the orientation arrows. Go to the menu bar and turn off the visualization of the fibers by un-checking View → Structure. Orientation arrows are visible only in 3D view. Switch to it by selecting View → 3D Rendering.

The direction of an arrow in a particular block shows the main fiber orientation in the block, and its length shows the strength of this main fiber orientation. The color of the arrows indicates the fiber solid volume fraction (SVF) in a block. The color range is green-yellow-orange-red. Assignment of color in a block depends on its SVF relative to the SVF of the other blocks. The block with the highest SVF gets a green arrow. The block with the lowest SVF gets a red arrow. When there is only one block (homogeneous material), the arrow is red.

For a homogeneous material structure (no subdivision), only one arrow appears in the center of the single block. Here, the short arrow pointing in the X-direction indicates that although the fibers’ main orientation is on the X-axis, there is a great deal of dispersion.

For a heterogeneous material structure, divided into 3x3x2 blocks, 18 arrows appear that occupy the centers of each of the 18 blocks. All arrows are oriented closely to the Y-axis. The range of colors indicates that the SVF of some blocks (green arrows) is higher than that of others (red arrows).

Besides the 3D orientation arrows it is possible to visualize the GOF file (if one was calculated). Click Load *.gof under the Fiber Orientation Visualization tab of the Result Viewer.

Select, e.g., to load the Orientation:AngleToX to get for each fiber segment the angle to the x axis.

In the Visualization panel, above the Visualization area, uncheck the check box in the Structure tab. In the Volume Field tab, deselect Visibility for the pore space (Material 00).
