Particle and thermal fluxes in divertor region of DIII-D discharges with neoclassical only effects


Four simulations without anomalous diffusion (tbl_diffusion_on=0) have been submitted on Hopper at NERSC. One simulation crashed after 12750 in the interpolation routines:

istep:        12750
 ?herm2ev:  xget=        NaN out of range  4.4710E-01 to  1.3519E+00
 ?herm2ev:  yget=        NaN out of range -8.5161E-01 to  8.5161E-01
 **EZspline** ERROR/WARNING #           96  occurred
 **EZspline** some error occurred in EZspline_derivative

This problem is still to be sorted out. Other simulations are completed. However, temperature and density profiles looks odd. In particular, there is a bump in the ion temperature profiles just after the separatrix
