xgc.f2d.#####.bp
Printed when: ? Output frequency: diag_f3d_period.
Moment calculations of the axisymmetric gyrocenter distribution function \(f\) on the Eulerian space velocity grid, i.e. \(\langle G \rangle_f = \int d\mathbf{v} \, G \, f(v_\perp, v_\parallel)\).
When variables end in _f0, its averaged over the adiabatic component of the distribution function, i.e. \(\langle G \rangle_{f0} = \int d\mathbf{v} \, G \, f_M \exp(-q (\phi - \phi_{00})/T)\).
When variables end in _df, its averaged over the non-adiabatic component of the distribution function, i.e. \(\langle G \rangle_{df} = \langle G \rangle_{f} - \langle G \rangle_{f0}\)
When para or parallel is in the name, the moment weighting includes the parallel velocity.
When poloidal is in the name, the moment weighting includes the poloidal velocity from the equations of motion, \(v_\theta = \frac{1}{B^*}\left[v_\parallel \mathbf{B}^*+\mathbf{v}_{dr} B\right] \cdot \hat{\theta}\)
When toroidal is in the name, the moment weighting includes the toroidal velocity from the equations of motion, \(v_\varphi = \frac{1}{B^*}\left[v_\parallel \mathbf{B}^*+\mathbf{v}_{dr} B\right] \cdot \hat{\varphi}\)
When rad or radial is in the name, the moment weighting includes the radial velocity with \(\nabla \psi\) from the equations of motion, \(v_r = \frac{1}{B^*}\left[v_\parallel \mathbf{B}^*+\mathbf{v}_{dr} B\right] \cdot \nabla \psi\)
