Determine plasma flux functions for various plasma parameters and plasma configurations.
copied from cf-staging / plasmaboundaries'This code computes and plots analytical solutions of the Grad-Shafranov (GS) equation for studying plasma equilibrium, stability and transport in fusion reactors based on the work of A. Cerfon and J. Freidberg. Details on the method can be found in "One size fits all" analytical solutions to the Grad-Shafranov equation, Physics of Plasmas 17 (2010).'
