GX_Simulator creates this type of model if the data structure imported from IDL contains, beside the mandatory and optional tags described  in the Input File Formatig Convention section of this document, three aditional tags coresponding to externally defined numerical distributions of  thermal electron density and temperature for all or a subset of the volume voxels.

A typical BxByBz-NT IDL structure is described below.

IDL> help,box,/str
** Structure <4a82558>, 9 tags, length=26900808, data length=26900804, refs=1:
BX FLOAT Array[128, 128, 128]
BY FLOAT Array[128, 128, 128]
BZ FLOAT Array[128, 128, 128]
N FLOAT Array[144579]
T FLOAT Array[144579]
DR DOUBLE Array[3]
LAT FLOAT 17.1310
LON FLOAT 36.3370
IDX LONG Array[144579]
  

Where the additional one dimensional array tags  N  and T  define the electron density and temperature in the volume voxels references by the one dimensinal index tag IDX .

If GX_Simulator recognizes this model type, it creates a Model Attributes page that contains magnetic field, density, and temperature scaling factor input fields, which may be used to lindependently scale the magnetic field, density, and temperature defined in the model.

The Model Attributes plot area may be used to display 2D  correlation plots of any combination of two of Bx, By, Bz, B, N, and T model parameters, or 1D distributions of those.

The numerical density and temperature internaly defined by a BxByBz-NT model are embeded by GX_Simulator in its global Coronal Model according to the mechanism described in the Integration of Numerical Models in the Global Coronal Model section of this document.
