I had added the header file prior to the run. For more information, given
below is the snippet of the code :
void Step3::make_grid ()
{
GridGenerator::hyper_cube (triangulation, -1, 1);
triangulation.begin_active()->face(0)->set_boundary_id(1);
triangulation.refine_global (5);
std::cout << "Number of active cells: "
<< triangulation.n_active_cells()
<< std::endl;
}
I then use:
VectorTools::interpolate_boundary_values (dof_handler,
1,
ConstantFunction<2>(1.),
boundary_values);
as given in the documentation.
