Hi All,
I have successfully computed the secondary electric field for 3D case as
described in the paper by Grayver, 2014. These field is declared as
BlockVector solution, where the block correspond to real and imaginary
parts.
Now I would like to compute total electric E (secondary plus
Praveen,
I have used FE_RaviartThomasNodal to solve induction equation on
Cartesian meshes which worked out very well.
Now I would like to solve Maxwell equations on general quad meshes. For
this I have to use FE_RaviartThomas, but I do not completely understand
this space.
I'm not sure

Well, when I asked the question, I did not know how to do it. I then saw
from my own answer to Jean-Paul's question that I could use a lower degree
FE_RaviartThomasNodal itself to get test functions for moments.
Thanks

Dear Maxi,
I'm going to put my foot down and say that, particularly as of late, you're
not giving your problems sufficient attention before posting them to the
forum. We have a set of guidelines

I am trying to implement example 26 using Newton's method and Sacado, in
order to get a better feeling for the method. As mentioned before, I had
problems with retaining the old solution when remeshing. Thus I rewrote my
remeshing sequence as
template
void HeatEquation::refine_mesh ()
Thanks for giving feedback as to what the source of the issue was. I'm glad
that you resolved your problem!

Found my problem, it was the remeshing. Whenever I was remeshing, I
basically killed the old solution, which then resulted in nan-values for
it. That in turn generated -nan-values for the system matrix.
