# TGYRO¶

## Quick links¶

## Overview¶

TGYRO is a parallel transport manager with the ability to call multiple
instances of TGLF and NEO in order to obtain steady-state temperature,
density and rotation profiles. The code was designed to operate with a
comparatively *sparse* radial mesh so as to minimize the number of calls
to the transport model.

In addition to its role as a transport code, TGYRO also operates as a job manager for ensembles of independent GYRO/CGYRO simulations.

## Data input¶

The primary TGYRO input file is input.tgyro, with profile data defined in input.profiles.

## Data output, python interface, and plotting¶

Although there is a description of output data, it is suggested that users use the python interface to output data.

## Transport equations and solution¶

We give a brief description of the transport equations, see Equations solved in TGYRO.
Unlike most other transport solvers, the solution algorithm in TGYRO is **not** based
on time-integration of the transport equations. Instead, the steady-state
equations are solved (see TGYRO Solver).
