Dear Daniel Thanks for your answer, the 7.1.0 version of step-12 seems also using the MeshWorker, i find the 6.2.1 version of step-12 without using MeshWorker: https://www.dealii.org/6.2.1/doxygen/deal.II/step_12.html
I want to repeat the numerical example of the references, which is a stokes-darcy problem in different parts of the domain. The stokes equation may takes DG basis functions. Actually, I also want to use the MeshWorker, what worried me is that I can't control MeshWorker by myself, it something likes I know the MeshWorker can do lots of thing, but I don't know how to use MeshWorker. I am just beginning to use deal.ii, and deal.ii seems a little complex to me. So I want to find some examples of MeshWorker. And I am wondering if it is there any more advices?
