Names:

DINA, and for the EU version DINA-CH

Author (Institution):

R.R. Khayrutdinov (TRINITI) and V.E. Lukash (RRC Kurchatov)
The DINA-CH Matlab SIMULINK version also involves V. Dokuka (TRINITI).
The DINA-CH joint development was supported by the CRPP through J.B. Lister, J-Y. Favez, D. Raju (detached from IPR, India)

Objectives:

Solution of the 1.5D free boundary equilibrium and transport evolution including the evolution of the PF control coil currents and the passive structure currents.
Full implementation of the equilibrium feedback is provided including magnetics diagnostics and power supplies.
The main purpose is to study non-linear discharge evolution for the general control, disruption and breakdown issues, to allow simulation of full tokamak discharges as realistically as possible.

Physics bases:

Diffusion of poloidal flux with a free boundary and arbitrary passive structure and active coil currents.
Diffusion of ion and electron energy.
Diffusion of particles.
Inclusion of spatially localised and flux-surface localised heating, alpha-heating.
Modelling of the sawtooth and the disruption with halo currents and runaway electrons generation
Modelling of breakdown under development.
Limited internal transport models (under continued development).
No Edge Modelling in present version, but under development.
Sources and sinks: Models for NBI, ECRH, LH, fusion reactions, Bremmsstrahlung/cyclotron radiation, have been incorporated in different versions.

Assumptions and limitations:

Axisymmetry

Status:

Mature; has been used on DIII-D, JT-60U, TCV, ASDEX-Upgrade, COMPASS-D.
