Transversely isotropic eight chain model. Individual chains are modeled as wormlike chains with an energy ψ^wlc parameterized in terms of the end-to-end length r. Eight chains are assembled in a transversely isotropic unit cell with dimensions a and b, and a characteristic orientation ν₀. The energy of each unit cell consists of the bulk energy ψ^blk, the energy of the eight individual chains ψ^chn, and their repulsive contributions ψ^rep.
