This can only happen if you are on a locally owned cell and the neighboring

Wasim,
we do not know what modifications you made to your program, and so there is
very little anyone can help you with the error. If I had to guess, you are
forgetting to call dof_handler.distribute_dofs() before you start to access
vertex dof indices.

Dear Wolfgang,
Thank you so much for your inputs. Indeed, Step-31 is a good example for
what I am looking for. However, I have a follow-up question regarding using
the *WorkStream* class based on TBB during the assembly stage when two
different dof_handlers are involved.
To be specific, in
Hello,
You are using a non-ghosted vector. You need to created a ghosted vector
and they assign the non-ghosted vector to the ghosted one.

I am trying to querry for the jump in my solution with
"get_jump_in_function_values"

Hello everyone.
I am working on the discontinuous-Galerkin solver, which is described in
tutorial step-76. In solver, time stepping is performed using the Low
Storage Runge Kutta method. The stage-wise computation is performed using
loop_cell_centric(). The solver uses MatrixFree class. I
