Functions

max_abs_coil_current(eq)	Given an equilibrium, return the maximum absolute coil current
max_coil_force(eq)
no_wall_intersection(eq)	Prevent intersection of LCFS with walls by returning inf if intersections are found
optimise(eq, controls, measure[, maxgen, N, ...])	Use Differential Evolution to optimise an Equilibrium https://en.wikipedia.org/wiki/Differential_evolution

Classes

CoilHeight(label[, minimum, maximum])	A control to modify the height of a specified coil
