S DELTA0 - Theory Group

S_DELTA0

Measure of the rate of change of average triangularity, $s_{\delta_0}\,\!$ , at the center of the radial simulation domain.

$s_{\delta_0} = r \, \frac{{\partial \delta_0}}{{\partial r}} .$

This is only active with RADIAL_PROFILE_METHOD=5.
When experimental profiles are used, the elongation as a function of radius is read from INPUT_profiles.
