Hello FEBio community,
Following this post (Link), I've managed to find a way of setting different fiber orientations among the same object. I separated my object into three parts, assigned a material property for each part, and wrote in the FEBio script the fiber direction I wanted to create, as following:
<material id="8" name="TibCartSuperficialZone" type="biphasic">
<phi0>0.2</phi0>
<fluid_density>1</fluid_density>
<solid type="solid mixture">
<solid type="spherical fiber distribution">
<alpha>0</alpha>
<beta>2.15</beta>
<ksi>10</ksi>
<fiber type="vector"> 1, 0, 0</fiber>
</solid>
<solid type="neo-Hookean">
<density>1</density>
<E>20</E>
<v>0.45</v>
</solid>
</solid>
<permeability type="perm-const-iso">
<perm>0.001</perm>
</permeability>
</material>
I obtained different results according to whether the fiber orientation has been implemented or not. But, as I'm not familiar with programming, I would like to know if this way of generating a fiber orientation is correct.
Thanks a lot and best regards,
Antoine
