Hi all!
I am currently working on the linear advection problem by using a DG
formulation, similar to the problem in step 12
https://www.dealii.org/current/doxygen/deal.II/step_12.html, but using a
mixed formulation as it is shown in step 20
https://www.dealii.org/current/doxygen/deal.II/step_20.html. I can solve
the problem without problems using a global refinement, however, when I
implement an adaptative refinement I have the following problem after the
1st refinement cycle
An error occurred in line <3792> of file
</home/arsen/Documents/instaladores/dealii/include/deal.II/dofs/dof_accessor.templates.h>
in function
void dealii::DoFCellAccessor<DoFHandlerType,
lda>::get_dof_indices(std::vector<unsigned int>&) const [with
DoFHandlerType = dealii::DoFHandler<2, 2>; bool level_dof_access = false]
The violated condition was:
this->active()
Additional information:
get_dof_indices() only works on active cells.
I have seen that some people had this problem a couple of years ago, but I
have not seen a proper solution to solve it.
Anyone knows how can I solve it?
Thank you so much,
Regards,
Juan Felipe Giraldo
