DG with pendant point
 
Hello ,i am working on adaptive DG for hyperbolic problem with triangular mesh. When refining the grid there are some hanging nodes on the cell boundary.when we use slope limiter (proposed by ChiWang Shu)the three neighboring elements are needed and but now there maybe two neighboring elements on one boundary or some boundary is a part of one boundary of another neighboring element . i am puzzled how to implement the slope limiter? is there anyone who knows the answer?

With best regards!

it is actually nonconforming mesh. how to implement the slope limiter in DG method? :confused:

Discontinuous Finite Elements
 
Hi,
I am quite well and I hope you will be same there. Anyone study the book of "Ben Q Li,Discontinuous Finite Elements in Fluid Dynamics and Heat Transfer". I want to discuss from that Book. I am very thankful of you.

Best Regards
