Trying to transfer solutions from an old grid to a new grid with
parallel::distributed::SolutionTransfer<dim, TrilinosWrappers::MPI::Vector,
DoFHandler<dim>> solution_transfer() and
solution_transfer.prepare_for_coarsening_and_refinement() fails with
An error occurred in line <71> of file <~/Downloads/git-files/dealii/source/
fe/fe_bernstein.cc> in function
const dealii::FullMatrix<double>& dealii::FE_Bernstein<dim, spacedim>::
get_restriction_matrix(unsigned int, const dealii::RefinementCase<dim>&)
const [with int dim = 2; int spacedim = 2]
The violated condition was:
false
Additional information:
You are trying to access the matrices that describe how to restrict a
finite element function from the children of one cell to the finite element
space defined on their parent (i.e., the 'restriction' or 'projection'
matrices). However, the current finite element can either not define this
sort of operation, or it has not yet been implemented.
Which function do I have to modify to make that work?
Thanks!
