I didn't knew that there was something like FE.shape_grad for integration on the reference cell. I thought it did by default isoparametric mapping with FEValues and JxW was for the mapping. FEValues takes care of converting gradient from reference to real cell. Mostly, this is what you will need when you implement a finite element method.  See this for some explanation https://dealii.org/current/doxygen/deal.II/group__FE__vs__Mapping__vs__FEValues.html and also this -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
