Check magnetic field strength for DESC equil
Bug description / feature request:
The magnetic field strength and current density come out wrong for the DESCequilibrium
.
Expected behavior:
Low field and high field side.
Proposed solution:
Switch to evaluation of contra-variant components B^rho
, B^theta
, B^zeta
and J^rho
, J^theta
, J^zeta
, respectively, instead of the now used covariant components.
Actually, I think the covariant components have a bug in DESC.
