BETAE UNIT - Theory Group

BETAE_UNIT

Electron beta at the center of the radial simulation domain, where the magnetic pressure is defined with respect to $B_{\rm unit}\,\!$ :

$\beta_e = \frac{8 \pi n_e T_e}{B_{\rm unit}^2} .$

This is meaningful for runs with non-experimental profiles (RADIAL_PROFILE_METHOD=1,5).
It is ignored when RADIAL_PROFILE_METHOD=3.
Simulations tend to become very expensive as this parameter moves beyond roughly 1/4th of the MHD critical beta.
