I can't seem to find a resource or tutorial that explains how anisotropic material properties are used within ANSYS, especially in regards to FSI with CFX and blood vessels. The help files give a tiny bit of information on anisotropic, hyperelastic models; but I don't see it being enough to apply to more than a cylinder.
My thought was that I could create a single material model and then apply individual coordinate frames to each element of the vessel wall (which would ideally give a different component breakdown of the strain for each element), but I haven't figured a way to do that. -Are users relying on a single coordinate frame for the entire model (it doesn't make sense for complicated geometry that doesn't follow an axis)? -If not, how are the principle directions being determined (or material model modified) and applied? -Is there a different, fully-coupled FSI, package that would make more sense to use for this problem? Thanks in advance for any help, Erick |
