4.3.3.3 Periodic von Mises Distribution
The fiber density distribution type “von-Mises-3d” models a transversely isotropic 3D distribution [34]. It corresponds to where are the components of in the local Cartesian basis of each element, when specified (see Section 4.1.1↑) or the global basis by default; and is the concentration parameter ( . The following material parameters need to be defined:
<b> | The concentration parameter | [ ] |

Example:
<distribution type="von-Mises-3d"> <b>0.5</b> </distribution>
