DLNNDR

Definition

Main ion logarithmic density gradient (dimensionless):

$- \frac{a}{n_1}\frac{\partial n_1}{\partial r} .$

Comments

This local parameter is used only when RADIAL_PROFILE_METHOD=1,5.
In order to satisfy plasma neutrality the following relation between density gradients must be satisfied:

DLNNDR_ELECTRON =

Z * NI_OVER_NE * DLNNDR +

Z_2 * NI_OVER_NE_2 * DLNNDR_2 +

Z_3 * NI_OVER_NE_3 * DLNNDR_3
