Dear Dune!<br>
I just had a look at the GenericReferenceElement class.<br>
I learned that said class has methods<br>
<br>
<pre class="fragment"><span class="keyword">template</span>< <span
class="keywordtype">int</span> codim >
FieldVector< ctype, dim >
<a class="code"
title="map a local coordinate on subentity (i,codim) into the reference element">global</a>( <span
class="keyword">const</span> FieldVector< ctype, dim-codim > &local, <span
class="keywordtype">int</span> i )<span class="keyword"></span></pre>
and<br>
<br>
<pre class="fragment"><span class="keyword">template</span>< <span
class="keywordtype">int</span> codim >
FieldVector< ctype, dim >
<a class="code"
title="map a local coordinate on subentity (i,codim) into the reference element">global</a>( <span
class="keyword">const</span> FieldVector< ctype, dim-codim > &local, <span
class="keywordtype">int</span> i, <span class="keywordtype">int</span> c )<span
class="keyword"> const</span>
</pre>
<pre class="fragment">Their documentations appear to be identical, with the exception of a
note saying "The runtime argument c is redundant and must equal codim"
for the second method. And indeed the method throws an exception
if c!=codim.
</pre>
<br>
Why do we have this seemingly pointless method as part<br>
of our grid interface?<br>
<br>
Best,<br>
