Understanding meq's function naming scheme
Codes:
- fbt Inverse equilibrium problem: given constraints and cost function in terms of
, B, coil (etc), find coil currents Ia. - liu Equilibrium reconstruction: given measurements, find
- fgs Forward solver: given Ia, Iv, p', TT' (or integral parameters), find
- fge Forward evolutive solver: given Va(t), integral parameters (t), find Ia(t), Iv(t),
- meq Generic functions for all three codes
Tokamaks [tok]:
- tcv : TCV tokamak
- rfx : RFX-mod
- create : CREATE ITER definition files
- ana : tokamak with user-specified geometry (through analytical formulas) for stand-alone tests
Functions naming scheme:
- [code].m : Main calling function
- [code]x.m: Retrieval of data
- [code]g.m: Code specific geometry calculations
- [code]c.m: Consolidate parameters, geometry and ancillary data for code
- [code]t.m: Solver / time stepper
- [code]x[tok].m: retrieve data for specific tokamak
- [code]w[tok].m: MDS writer for code output
- [code]g[tok].m: Code-specific geometry calculations
- meqg[tok].m: Geometry definition for given tokamak [tok]
- meqp[tok].m: Main parameters of a given device
Main data structures
- L: General parameters structure
- L.P: User-set Parameters
- L.G: Geometry parameters
- L.T: Tunable parameters that only affect [code]t.m [not used yet]
- L.*: Parameters computed from L.P, L.G by [code]c.m
- LX: Input data structure
- LY: Output data structure
