Function Documentation

use_collocation_evaluation()

bool Portable::internal::use_collocation_evaluation ( const unsigned int fe_degree, const unsigned int n_q_points_1d )

constexpr

Helper function to specify whether a transformation to collocation should be used: It should give correct results (first condition), we need to be able to initialize the fields in shape_info.templates.h from the polynomials (second condition), and it should be the most efficient choice in terms of operation counts (third condition).

resolve_hanging_nodes()

template<int dim, int fe_degree, bool transpose, typename Number, typename ViewType>
