Yiyang,
I am not quite sure why, but the code
estimated_error_per_cell = distributed_error_per_cell;
generates an incorrect result. You can replace it with
for(auto cell = tria.begin_active(); cell != tria.end(); ++cell)
if(cell->is_locally_owned())
estimated_error_per_cell(cell->active_cell_index()) =
distributed_error_per_cell(cell->active_cell_index());
Can you try if that works for you?
I will continue to investigate what is going on.
