OK, slowly finding the detailed information I need. I still have lots to learn and understand.
reading /deal.II/deal.II/include/fe/fe_values.h am I correct in reading shape_hessian is now shape_2nd_derivative ? There was an "etc." above in the comments, yet I do not see shape_3rd_derivative shape_4th_derivative These are what I was looking for in my previous post. For example, the three dimensional beam problem has fourth derivatives in the PDE in all dimensions. If I was 50 years younger, I would consider investing the time to extend deal.II to four dimensions, x,y,z,t deal.II is a significant accomplishment. A very powerful PDE tool kit. I have a long way to go to learn the "deal.II diction" as you say, and I have to understand the "abstractions" in order to use them.
