Dear Dr.Bangerth,
I found it just before, it is on the page of FEValuesView (
https://www.dealii.org/current/doxygen/deal.II/classFEValuesViews_1_1Vector.html).
Thank you very much!
Best regards,
Yuesu

Dear all,
I want to contract the gradient tensor with another vector, such as
T_ij*n_j, the gradient tensor is d_j u_i (d is the partial differential
operator). I am wondering what is the first index of gradient tensor, i or
j? Thank you !
Best regards,
Yuesu
