Hi all, I have a confusion regarding 4th order symmetric tensor. I need the fourth order symmetric tensor \mathcal S, as defined in step 44. After defining \mathcal S in the introduction, it is mentioned that "The fourth-order SymmetricTensor <https://dealii.org/8.4.0/doxygen/deal.II/classSymmetricTensor.html> returned by identity_tensor() is \mathcal S". However, in the code this command has been used to get II (same as \mathcal I), i.e.
template <int dim>const SymmetricTensor<4, dim> <https://dealii.org/8.4.0/doxygen/deal.II/classSymmetricTensor.html> StandardTensors<dim>::II = identity_tensor<dim>(); I am confused here, because \mathcal I and \mathcal S are two different tensors. If anyone can clearly tell me which command to be used to get \mathcal I and which one to get \mathcal S, will be helpful for me.
