Nik, it sounds like you've already figured out the big building blocks. Indeed, the right way to deal with this is to use different finite elements on the different parts of the domain (like in step-46), and then to sort DoFs by vector component -- which then automatically produces the block

Dear Wolfgang, Maybe I had not make my question clear. I dont think the question we encountered is not graphical output, instead, I think the the problem we encountered is numerical issue in Deal II. For example, when we take thermal conductivity as 1e6 (the real value of the problem), there alway
