[deal.II] where and how should I use the MeshWorker class? how should I do to implement DG without MeshWorker?

Hi, I'm reading the step-12, and i get confused that where and how should I use the MeshWorker class? The MeshWorker class seems just using in the DG examples. But I do not think it is a good idea to use MeshWorker in my problems, the problems, I will treat, maybe a little complicated, it c

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

Dear Wolfgang , Thanks for your advice, I have read the 6.2.1 version of step-12, and I know how to deal DG without using MeshWorker. What's more there is the 6.2.1 version of step-12 without using MeshWorker, if someone needs. https://www.dealii.org/6.2.1/doxygen/deal.II/step_12.html 在 2016年8
