DataPostprocessorInputs::CommonInputs< spacedim >::get_cell()

[shuitao zhang]

Hi everyone,

I have one question when i using DoFHandler<dim, spacedim>::cell_iterator DataPostprocessorInputs::CommonInputs< spacedim >::get_cell() const. 

The code I write this:

template <int dim>

class BoundaryIds : public DataPostprocessorScalar<dim>

{

public:

BoundaryIds()

: DataPostprocessorScalar<dim>("boundary_id", update_quadrature_points)

{}

virtual void

evaluate_scalar_field(

const DataPostprocessorInputs::Scalar<dim> &inputs,

std::vector<Vector<double>> &computed_quantities) const override

{

AssertDimension(computed_quantities.size(),

inputs.solution_values.size());

// Get the cell and face we are currently dealing with:

const typename DoFHandler<dim>::active_cell_iterator cell =

inputs.template get_cell<dim>();

const unsigned int face = inputs.get_face_number();

// Then fill the output fields with the boundary_id of the face

for (auto &output : computed_quantities)

{

AssertDimension(output.size(), 1);

output(0) = cell->face(face)->boundary_id();

}

}

};

And my error is:

no maching function for call to " DataPostprocessorInputs::CommonInputs< spacedim >::get_cell() "

Could someone can help me?

Thanks very much!

Best wishes,

zhang

Zhang:
What version of deal.II are you using? It used to be the case that you had to
write
inputs.template get_cell<DoFHandler<dim>>();
and only in newer versions of deal.II you can write
inputs.template get_cell<dim>();

Best
