Dear community,
I tried to put adaptive_refinement function into separate files. It works pretty well without parallel. But I get a link error when using the parallel framework, which said: undefined reference to `void dealii::parallel::distributed::GridRefinement::refine_and_coarsen_fixed_number<1, dealii::Vector<float>, 1>(dealii::parallel::distributed::Triangulation<1, 1>&, dealii::Vector<float> const&, double, double, unsigned int)' The weird thing is if I do not use this template class, namely use this refinement function directly just like step-40, it runs without that link error. However, I really want to separate it so that it can be used in different cases. The following is the code. Any suggestions would be appreciated. - grid_handler.h header file: template <int dim>class GridHandler { public: static void adaptive_refinement(const DoFHandler<dim> &dof_handler, const LA::MPI::Vector &solution, parallel::distributed::Triangulation<dim> &triangulation); } - grid_handler.cc source file: template<int dim>void GridHandler<dim>::adaptive_refinement(const DoFHandler<dim> &dof_handler, const LA::MPI::Vector &solution, parallel::distributed::Triangulation<dim> &triangulation) { Vector<float> estimated_error_per_cell(triangulation.n_active_cells()); KellyErrorEstimator<dim>::estimate(dof_handler, QGauss<dim-1>(dof_handler.get_fe().degree+2), typename FunctionMap<dim>::type(), solution, estimated_error_per_cell); // Refine and Coarsen parallel::distributed::GridRefinement::refine_and_coarsen_fixed_number(triangulation, estimated_error_per_cell, 0.3, 0.03);// GridRefinement::refine_and_coarsen_fixed_number(triangulation,// estimated_error_per_cell,// 0.3,// 0.03); triangulation.execute_coarsening_and_refinement(); } // Explicit instantiationstemplate class GridHandler<1>;template class GridHandler<2>;template class GridHandler<3>; Thank you!
