<div class="moz-cite-prefix">Hi Ganesh.<br>
I think this is the wrong place to pose that question because the
answer is<br>
going to depend on the underlying fem package you use. Perhaps
better<br>
to put it for example to the dune-fem mailing list (and I'll
answer it from there).<br>

<div>I recall one of my old posts on this topic: <a

href="http://lists.dune-project.org/pipermail/dune/2015-February/013459.html">http://lists.dune-project.org/pipermail/dune/2015-February/013459.html</a><br>

<div>In order to "build" a polygon: I first create a mesh the
usual way (either Gmsh or in Dune itself) and then partition
it using ParMETIS to agglomerate the finite elements. One
such agglomerated unit is one of my polygons and so on. <br>
<br>
Now, I am trying to understand if it will be possible to
treat these polygons (which are basically agglomerated
finite elements) as finite elements in their own right in
Dune? I can compute a given function f at the quadrature
points inside the polygons and do int_Omega f, but
obviously I need more. For eg, if an agglomeration can be
treated as a finite element, how do I evaluate the basis
function phi_i, its derivatives and then do a subsequent
assembly for them? To be precise, the methods which are
already in place to do exactly this, can I use them to
operate on my polygons? For eg. when reusing the dune-fem
code, I would like to use methods such as
localFunction.evaluate, rhsLocal.axpy and rhs.communicate
but I do not understand how to and what to change in order
to achieve this.<br>
