Paras -- it's a bug in deal.II: The assertion you run into is a bit overzealous and flags something that is perfectly legitimate. I'll fix the actual problem later this weekend, but here is a workaround for you: Where you call the build_patches() function, replace dataOutPrimary.build_patches(qMapping, nSubdivisions); by dataOutPrimary.build_patches(qMapping, nSubdivisions, DataOut<dim>::curved_inner_cells); and your code should work (doing essentially the same as before -- maybe even in a more correct way).
