Hello Jason,
get_function_hessians is also implemented for FEValuesViews::Vector.

Hello All,
I am interested in computing the second derivatives of a vector-valued
finite element, using FEValuesExtractors. My compiler says that this
function is not implemented in FEValuesViews::Vector
<http://www.dealii.org/developer/doxygen/deal.II/classFEValuesViews_1_1Vector.html>,
and I looked and saw that only the get_function_hessians for scalar
finite elements is implemented.
I was wondering if there is a reason that there is no equivalent
function to get_function_hessians
<http://www.dealii.org/developer/doxygen/deal.II/classFEValuesBase.html#ab702294a61d3ede128e959764a67f624>
from FEValuesBase, or if it just needs to be created, or perhaps I am
misunderstanding how FEValueViews works.
Thank you for your assistance,
-Jason Sheldon
PS: Thank you for the advice concerning FESystems, from my previous
query. I was able to implement the suggestions.
