Thanks, I did try looking at the documentation for FEValuesViews::Vector <http://www.dealii.org/8.5.0/doxygen/deal.II/classFEValuesViews_1_1Vector.html>< dim, spacedim >::hessian(const unsigned int shape_function, const unsigned int q_point) before coming here, and all it provides is
"Return the Hessian (the tensor of rank 2 of all second derivatives) of the vector components selected by this view, for the shape function and quadrature point selected by the arguments." I looked in fe_values.h to see if it was commented in the implementation and all that I see there is hessian_type return_value; for (unsigned int d=0; d <http://www.dealii.org/8.5.0/doxygen/deal.II/namespacePhysics_1_1Elasticity_1_1Kinematics.html#a15728437b942dab0b0042eb06a407d2c> <dim; ++d <http://www.dealii.org/8.5.0/doxygen/deal.II/namespacePhysics_1_1Elasticity_1_1Kinematics.html#a15728437b942dab0b0042eb06a407d2c> ) if (shape_function_data[shape_function]. is_nonzero_shape_function_component[d]) return_value[d] = fe_values->finite_element_output.shape_hessians[ shape_function_data[shape_function].row_index[d]][q_point]; which I'm not quite sure how to parse. The comments in the header file only say "same as for the scalar case except that we have one more index." (the added index is d). This is why I brought my question here. -- 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.
