Spectral CPO model of polycrystalline materials that can:

• Model lattice rotation, discontinuous DRX, and rotation/continuous DRX.
• Calculate CPO-induced viscous anisotropies using Sachs/Taylor homogenizations.
• Calculate elastic P- and S-wave velocities using Voigt/Reuss homogenizations.
• Provide expressions for forward+inverse orthotropic and transversely isotropic rheologies.
• Convert between structure tensors and spectral expansions coefficients.
• Be integrated with finite-element codes such as Elmer and FEniCS.

Q	A
What $L$ are possible?	Any $4\leq L\leq 20$. If higher $L$ are required: 1. cd src/include && python3 make_gaunt_coefs.py L (replacing L) 2. make clean && make
