Now I see! Thanks for the clarification.<br>
<br>
So are you connecting the vertices to themselves? What is the
element type in VTK for such an element?<br>

Perhaps, I'm not fully understanding your questions, but it
is certainly possible to create vertices in MOAB and then
use them directly in your analysis. There is no need to
create an element if, in fact, all you need are the
vertices. Each vertex can be tagged with data in the same
way that an element can be.<br>
<br>
I hope that is helpful,<br>
Paul<br>

Hello,<br>
Moab does not have elements with a single vertex.
Is this what you are trying to do?<span

A vertex (node) is represented with an entity

dummy is 0, which is an invalid handle,
but should be the handle(s) of the
entities whose connectivity you're
setting; I suspect what you want there is
*vertices.begin(). And you can't set
connectivity until you make an element, so
you need to call create_element, probably
with the number of verts per element as 1
and the connectivity just the single
vertex defining the point element.<br>
