TRANSP v19.1

GENRAY for Electron Cyclotron calculations

The ray tracing code GENRAY can now be used for any tokamak, by setting NLGEN_ECH=.T, with the same settings that are used for TORAY_GA. The default number of rays is 48 and this cannot be modified from the TRANSP namelist. GENRAY EC can be run in parallel, with number of CPU equal to the number of rays; this option is activated by setting NGENRAY_PSERVE=1. Please refer to the online help for MPI options.
GENRAY EC is not coupled to CQL3D yet. This is because the corrections to the current drive would be small in this case and the error made using CQL3D would be larger than the error made neglecting these corrections. In fact, it should be remembered that CQL3D calculates the total current, thus the Ohmic contribution needs to be subtracted to have the EC driven current. This contribution depends on the assumptions on the model for the plasma resistivity.

Hager parametrization for the bootstrap current

This implementation is based on the work done by R. Hager [Phys. Plasmas 23, 042503 (2016)]. The Sauter formulation is being modified to include higher collisionality regimes, based on calculations run with XGCA.
The parametrization by Hager can be activated by selecting the flag NLBOOTHAGER=.T. in addition to NLBOOT=.T..

Additional outputs for TGLF

Following request from several users, additional variables for the high dimensionality data from TGLF have been added to the TRANSP output file. Because of the size of the files, these adidtional output are stored only when NLGROWTH_TGLF=.T..
The output is function of time, ky and rho and can be visualized in the OMFIT interface.
