It sounds like there's support for 2nd order hexes which can be used
as cylindrical mesh elements but in a Cartesian coordinate system?<br>
<br>
<br>
<pre wrap="">what is a cylindrical mesh element?
maybe expressed in cylindrical coord system?
there is some support for spherical coord system for some special nc meshes (basically quads are in
lat / lon coordinates)
anyway, I don't understand what is the need</pre>
Iulian, <br>

There is a researcher who wants to use the discretize_geom function
in <a href="http://pyne.io/"><tt>PyNE</tt></a> to get the volume
fractions of some geometry which is in cylindrical coordinates.
Essentially, the answer is yes to your second question. <br>

It's certainly possible to represent a cylindrical mesh with
2nd-order hexes (and prisms at the center).
<br>
<br>
Determining volume fractions via ray-firing using DAGMC is not
currently supported on 2nd-order mesh elements, however.

I think there was a thread about this a while ago... I recently
got an email from someone at GWU asking about a geometry/mesh
library which can do volume fractions in cylindrical
coordinates. They were originally looking for a way to do this
via the pytaps interface, but are willing to use other methods
if they are available.
<br>
<br>
I feel like I remember someone mentioning that there is access
to cylindrical mesh elements in MOAB, but I couldn't be sure. Is
this true or am I daydreaming?
