Hi I am again tinkering with my favorite tutorial step 23 and I am have a question again on how to move forward. What I am attempting to do now is redo this setup but rather than using helper functions to create the system matrix and RHS, I am trying to build the system by looping over the cells.
My question stems from how I get the appropriate local values from vectors to use in the loops. So in step 23 you would want to get values from old_solution_u and old_solution_v. Now I looked at other tutorials and I not 100% sure they had a similar need. In looking over the documentation my guess is that I would use the overloaded get_function_values void FEValuesBase <https://www.dealii.org/current/doxygen/deal.II/classFEValuesBase.html>< dim, spacedim >::get_function_values ( const InputVector & fe_function, const ArrayView <https://www.dealii.org/current/doxygen/deal.II/classArrayView.html>< const types::global_dof_index <https://www.dealii.org/current/doxygen/deal.II/namespacetypes.html#a3543786f7dc7c57385fc923a6afd5917> > & indices, std::vector< typename InputVector::value_type > & values ) Is this correct? Also how would I deal with quadrature points in this instance in this context. Any help would be much appreciated?
