Below is a link to radial profiles of the flux surface averaged potential (the phi(0,0) mode) at six times for my base case run. This is (e Phi / T_i) (L_ne / rho_i), so my curves should be divided by eta_i=3.11 to compare to Andris's curves, which are (e Phi / T_i) (L_T / rho_i) (Andris's PDF file is here). Eyeballing it very roughly, the levels look comparable to Andris's, but time averaged spectra are needed for a quantitative comparison.
Phi00 plots vs. minor radius for base case from
gyrofluid run
The six time slices are at: 345, 600, 840, 1067, 1294, and 1515 L_T/v_ti. The time history of chi_i for this run is the first plot on this page.
Next are radial profiles of the flux surface averaged potential at four times for my -30% case run. Now these curves should be divided by eta_i=2.16 to compare to Andris's (Andris's PDF file is here). (I used R/L_T = 4.8 for this run.) This case looks significantly different from Andris's-- the gyrofluid phi(0,0) is not stationary late in the run.
Phi00 plots vs. minor radius for -30% case from
gyrofluid run
The four time slices are at: 333, 624, 892, and 1169 L_T/v_ti. The time history of chi_i for this run is the blue curve here.
