<div style="direction: ltr;font-family: Tahoma;color: #000000;font-size: 10pt;">Hi Nico,<br>
Sorry I missed your message<br>
I modified one of the examples to construct all edges and faces, and output them in some files<br>
<br>
after compiling it, you can launch it with <br>
<br>
./HelloMOAB<br>
<br>
or <br>
./HelloMOAB <other_file> <br>
<br>
other_file can be any file that can be loaded in MOAB, in serial (for example, a gmsh file)<br>
<br>
for parallel IO, you can look at HelloParMOAB example, or tests in test/parallel<br>
<br>
<br>
There is a list of examples on doxygen page, with more links on how is data accessed.<br>

<div dir="ltr">Absolutely!
<div><br>
</div>
<div>I'm interested to see</div>
<div> * how I/O works,</div>
<div> * how edges/faces arecreated,</div>
<div> * how relationships are queried (Which cells does this face border on? Which nodes does this cell have? etc)</div>
<div><br>
</div>
<div>If there's an example in the sources, I'd be more than happy to look at that, too, of course.</div>

<div>Cheers,</div>

<div><br>
</div>
<div>For me, long means (much) longer than the actual (linear) solver in the end. On a test cube [1] of 140k tets and 27k nodes, creating edges takes about one minutes, faces about two (on one core that is). The linear solver in the end takes about seven seconds.</div>

<div dir="ltr">hmmm, that is too long, indeed.<br>
<br>
For moab, creating the edges and/or faces for that size of a mesh is on the order of seconds, on a laptop<br>
<br>
I will write a small example if you are interested <br>
