Hello Arun,
it is in the fe_values.cc/.h files. But you do not have to search for
it. You have just to download deal.II using svn and recompile it. Then
it should be available in your copy of deal.II, too.
Best Regards,
Markus

Hello Markus,
I am searching for the curl function that you implemented within svn
link and not sure what to look out for. Could you tell me the
name/location of the function within this link ?
http://www.dealii.org/svn/dealii/trunk/deal.II/
Too bad I cannot even locate it :(
Arun.

Hello Wolfgang,
I already implemented this function some time ago, but planned to
send it all together as one package, when the higher order Nédélec
elements are ready to release. I will send the curl function to
you today such that it can be included.
Best Regards,
Markus

After going through the tutorials and reports I am slowly
getting
familiar with deal. Very good library to learn for sure
because of its
flexibility. I am wondering how to implement maxwell's
equation whose
weak form will have (curl U, curl V). How can I implement
this ? I found
a report on Nedelec elements by Anna which talks about
this issue but I
haven't completely followed it yet in terms of its
implementation in
deal. Can someone provide some hints ?
You would simply have to choose the FE_Nedelec class.
Assembling the
bilinear form then proceeds as as discussed in the
documentation module on
vector-valued problems.
It might be worthwhile to implement a curl function so that
you can do
FEValuesExtractors::Vector E(0);
local_matrix(i,j)
+= fe_values[E].curl(i,q) * ...
Right now you would have to compute the curl from the
components of the
gradient matrix but it would be simpler if a function
FEValuesViews::Vector::curl
existed. Let me know if you want help implementing such a
function.
