1D diagnostics

xgc.oneddiag.bp contains diagnostics of flux-surface averaged quantities.

Printed when input parameter diag_1d_on=.true.
Output frequency controlled by input parameter diag_1d_period

Remarks

There are two radial discretizations in the 1D diagnostics: one set by the input parameter sml_00_npsi and one set by the number of closed flux surfaces crossing the lower-field-side midplane (# flux surfaces). There can be narrow flux surfaces that do not cross the lower-field-side midplane and these are not included in the default 1D diagnostics.

For neoclassical simulations (XGCa) it is advisable to calculate the proper flux-surface averaged fluxes by using the 2D diagnostics, and either the node volumes in Mesh or the flux-surface averaging matrix in Matrix operations. The reason is that the neoclassical fluxes are so small that it is important to accurately split the adiabatic and non-adiabatic parts of the distribution function.
