Hi Denis,
Actually I still need some help regarding this. The program builds but
cannot execute and I get an error of Segmentation fault:11
EdithMac:code_test Edith$ make
[ 33%] Building CXX object
CMakeFiles/Helmholtz_GFEM3.dir/source/functions.cc.o
[ 66%] Building CXX object
CMakeFiles/Helmholtz_GFEM3.dir/source/Helmholtz_GFEM3.cc.o
[100%] *Linking CXX executable Helmholtz_GFEM3*
[100%] Built target Helmholtz_GFEM3
EdithMac:code_test Edith$ Helmholtz_GFEM3
Segmentation fault: 11
Since I wanted to test the constructor, this program is only running a
make_grid() class function that makes the triangulation and should output
the number of cells.
For the constructor, Apart from the FE_Enriched<dim > fe_enriched
object, I created a FE_Q<dim> fe object in my class to be able to pass it
by address as in the code below.
Hope you can give some ideas of what is wrong with it..
template <int dim>
Helmholtz_GFE2<dim>::Helmholtz_GFE2 ():
fe_enriched (
& fe ,
{&fe },
{{
[=] (const typename Triangulation<dim>::cell_iterator &)
-> const Function<dim> * {return & enrich1;},
[=] (const typename Triangulation<dim>::cell_iterator &)
-> const Function<dim> * {return & enrich2;}
}}
),
fe (1),
dof_handler (triangulation),
enrich1 (k[0]),
enrich2 (k[1])
{
}
