dG jump term on surface

NGSolve

Is it possible to implement a dG method on a surface mesh? (not HDG). This requires computing the jump in the co-normal derivative of a Lagrange finite element function across a mesh edge. Not only that, but one needs the product of the jump in the Trial function * jump in the Test function.

It is clear how to do this on a flat domain from the examples. And I see the HDG on a surface example, but that does not have a product of jumps of Test and Trial. Is there an example of this somewhere?

no, as far as I am aware DG on surfaces is not supported and not on the short-time todo list.

Enjoy HDG :slight_smile:

Yes, I know (from another post). I need it for defining a discrete H^2 inner product. I was able to find another way (hack) to do it, though. So, it’s fine.
