<br>
Thanks for your reply. <br>
<br>
Yes, I only labels the vertex because I am doing the finite
element method where I only need the vertex label. Do you mean
that I need to label the faces and get the vertex label from the
face label?<br>
<br>
Thanks,<br>

I am using the DMRefine_Plex to refine a mesh. In the
coarse mesh, it has a label "Vertex Sets" to mark the
boundary nodes. I found that the DMRefine_Plex did not
refine this label.<br>
<br>
For example, in the coarse mesh, there are 100 nodes on
the boundary, that is the number of nodes in the label is
100. In the refined mesh (uniformly refined), the number
of nodes in the label should be larger than 100, but I
found that this number is still 100, which means the newly
added nodes on the boundary were not added to the label.<br>
<br>
But I need a refined label to set the boundary conditions.
Anyone can tell me how to get a refined Vertex Sets label?<br>

<div>All operations are topological in Plex, not geometric.
When we refine, we split edges (for instance) and the new
vertex inserted</div>
<div>inherits the labels from the edge that was split. I am
guessing that you only labels the vertices.</div>
