Thanks for your reply. I did not know I could just pass the higher order
mapping. If I omit DataOut<dim>::curved_inner_cells, then it works.
However, I pursue domains with curved inner cells. Following your
suggestion, I do:
data_out.build_patches (MappingQGeneric<dim>(max_degree), 8, DataOut<dim>::
curved_inner_cells);
and get the errors:

Any ideas?
