The General Atomics GACODE Suite (GLF23/TGLF/NEO/GYRO/TGYRO)
GLF23 is the original gyroLandaufluid model with a simple system of moment equations and a trial Gaussian wavefunction. It models the physics of
 trapped electron modes (TEM),
 ion and electron temperature gradient (ITG, ETG) modes
 electromagnetic kinetic ballooning (KB) modes.
 ExB velocity shear
TGLF is the nextgeneration gyroLandaufluid model that improves upon the accuracy of its predecessor, GLF23, using a more accurate system of moment equations and an eigenmode solution method that is valid for shaped geometry and finite aspect ratio. It captures the physics of
 trapped ion and electron modes (TIM, TEM),
 ion and electron temperature gradient (ITG, ETG) modes
 electromagnetic kinetic ballooning (KB) modes.
 ExB velocity shear
NEO is a multispecies driftkinetic solver which enables a firstprinciples solution of the local neoclassical transport problem. It has the capability to treat
 any number of Maxwellian species with arbitrary charge and mass.
 full collisional coupling of all species using the full linearized FokkerPlanck collision operator
 rapid toroidal rotation (including centrifugal effects)
 general (shaped) or simple circular plasmas
 experimental or userdefined physical parameters.
GYRO is a nonlinear tokamak microturbulence package designed to run on nearly all modern computing platforms, from an ultraportable laptop to the world's largest CRAY XT4/XT5 and IBM Blue Gene systems. Developed at General Atomics, GYRO uses a fixed (Eulerian) grid to solve the 5D gyrokineticMaxwell equations. Operation is flexible, with the capability to treat
 a local (fluxtube) or global radial domain, in a full or partial torus
 general (shaped) or simple circular plasmas
 adiabatic, driftkinetic or gyrokinetic electrons
 electrostatic, transverse and compressional electromagnetic fluctuations
 experimental or userdefined physical parameters
TGYRO is a parallel transport manager with the ability to call multiple instances of GYRO and NEO in order to obtain steadystate temperature and density profiles. It has the capability to include
 turbulent fluxes from GYRO, TGLF or the simple IFSPPPL model.
 neoclassical fluxes from NEO, or from simple HintonHazeltine theory.
