<p>hi Matt,</p>
<p>A couple of years ago we discussed adding support for 6-node
wedge cells in DMPlex- the hurdle being that at present DMPlex
doesn't support cells with faces of different shapes (see below)-
and you said it could be done, if and when I needed it.<br>
</p>
<p>People are starting to want to use my code on real models now,
many of which have 6-node wedge cells. So it would be very handy
to have support for those in DMPlex fairly soon if possible.</p>
<p>Any chance you would be able to take a look at it? In principle I
would be happy to help if I can. I have started looking at
plexinterpolate.c to try and see how it works, but at this stage
I'm not at all confident that I understand the subtleties.</p>
<p>Cheers, Adrian<br>

Yeah, I was afraid that might be the workaround ;-) It seems
to me that for a large unstructured mesh, creating the whole
DAG would basically amount to duplicating what the very handy
DMPlexInterpolate() function does.<br>

<div>The problem here is that if I allow faces of
different shapes, I have to keep track of the shape
of each</div>
<div>face when I make it. This is possible, and I
have added it to the TODO list, but I think it will
be a while</div>
<div>before I get to it. If you want to try doing it,
I would help.</div>

I'd have to get more familiar with how it works first, and it
probably isn't top of my priority list either at present- I
can continue getting my code together without support for
wedge cells at the moment. But at some point I will need it.</blockquote>
<br>
Okay, when you need it, we will make it work.<br>
