<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hello,<br>
Moab does not have elements with a single vertex. Is this what you are trying to do?
<br>
A vertex (node) is represented with an entity handle of type MBVERTEX, and you can get coordinates for it<br>
<br>
I am not sure what are you trying to do.<br>
Best Regards,<br>
Iulian<br>

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>

<br>
I've got the following problem:<br>
<br>
I want to create vertex entities, ie create the points and vertex entities using those points.<br>
So I've create a set of vertices from an array of coordinates.<br>
And If you try to set the connectivity for every point you get Error code 4 (MB_ENTITY_NOT_FOUND).<br>
<br>
This is my code:<br>
<br>
double points[6]={1,0,0, 0,1,0, 0,0,1};<br>
Range vertices;<br>
rval = moab.create_vertices(points,2,vertices); CHKERR_PETSC(rval);<br>
EntityHandle dummy=0;<br>
rval = moab.set_connectivity(dummy,vertexlist,1); CHKERR_PETSC(rval); //Error code 4<br>
<br>
Any suggestions how to overcome this problem.<br>
<br>
Kind regards,<br>
<br>
