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.
