The settings for TRANSPORT can be done inside the CONVERGENCE LOOP composite actor. Therefore please do:
ETS constructs the total transport coefficients from the combination of Anomalous transport (model choice), Neoclassical transport (model choice) and Database transport (transport coefficients be saved to the input shot)
D_tot = D_DB*M_DB + D_AN*M_AN + D_NC*M_NC
You should choose from the list of evailable models in each cathegory or switch it OFF
The list of available transport models can be found here.
In this section you define how total transport coefficients for main ions should be constructed from contributions provided by different models. You need to provide the multipliers for Anomalous, Neoclassical and Database contributions, which will determine their weights in total transport coefficient.
You also can add the constant background level for each coefficient (ion coefficients are expected to be the string {1:NION}, separated by commas)
In this section you define how total transport coefficients for impurity ions should be constructed from contributions provided by different models. You need to provide the multipliers for Anomalous, Neoclassical and Database contributions, which will determine their weights in total transport coefficient.
You also can add the constant background level for each coefficient (coefficients are expected to be the string {1:NIMP}, separated by commas)
In addition, there is an option to import the Anomalous component of transport coefficient from_first_ion or from_electrons (the same anomalous contribution will be added to all impurity components, all ionization states)
In this section you can artificially supress the transport outside of specified RHO_TOR_NORM_ETB. Total transport coefficients for all transport channels (ne, ni, nz, Te, Ti,...) will be reduced to constant values specified below (ion and impurity coefficients are expected to be the strings {1:NION}) and {1:NIMP} respectively)
Profiles of the total transport coefficient for each channel are obtained from the the individual contributions (Data Base, Anomalous, Neoclassical and Background) as a summ of all activated transport models multiplied with coefficients specified on the interface of the composite actor.
X_tot = X_DB*DBM + X_AN*ANM + X_NC*NCM + X_BG*BGM!!! Note, that contributions to all transport equations will be multiplied with the same value.
The fine tuning of of transport coefficients can be done through editing the XML code parameters of the transport combiner actor:
If you select OFF contributions
from all transport models to this channel will be nullified; If you
select from_input_CPOs the
transport channel will be activated, and the total transport
coefficient will be combined from active tranport models; For
convective velocity there is an additional
option fixed_V_over_D_ratio,
by selecting this the combiner will ignore the convective components
provided by transport nmodels. The convective velocity will be
determined from the total diffusion coefficient by applying fixed V/D
ratio (for inward pinch the values should be negative!).
For all active channels you can adjust multipliers for combining contributions from different
transport models (array of four space separated values is expected):
