Detailed Description

Evaluation of the safety factor q based on direct integration of \( q(\psi_0) = \frac{1}{2\pi} \int d\Theta \frac{B^\varphi}{B^\Theta} \).

Attention

Return value undefined if evaluated outside the closed fieldline region, but the function always returns, it won't throw an error or something

Template Parameters

container

A data container class for which the blas1 functionality is overloaded. We assume that container is copyable/assignable and has a swap member function. Currently this is one of dg::HVec, dg::DVec, dg::MHVec or dg::MDVec std::vector<dg::HVec>, std::vector<dg::DVec>, std::vector<dg::MHVec> or std::vector<dg::MDVec> .
