Zone intensity data file	<RUN_NAME>_<time_index>.zdi
Zone specific data file	<RUN_NAME>_<time_index>_<zone_number>.zdt

 

Not all of the files may be present, depending on the details of the simulation.

Copy of workspace file - *.swc:

This is an exact copy of the workspace in Spect3D at the time the simulation started.

Energy and Transition data file - *.etd:

The file contains a listing of the atomic energy levels and transitions considered in the calculation. It is used to produce the transitions table used with the spectral plots.

The following files are present for each time step.

Log file - *.log

Contains some of the atomic data used in the simulation plus other miscellaneous information. May contain error messages if the simulation failed.

Detector images file - *.dti

Contains the following information and data for the image at the detector. View sample dti file

• The format type of the file, the run name and the date and time the calculation was performed.
• The image plane grid parameters:
  • the number of horizontal pixels - N[x]
  • the number of vertical pixels - N[y]
  • the sizes of the horizontal and vertical pixels in cm - D[x] and D[y]
• The total number of filter response functions, followed by a breakdown of the number of FFC and XRD filter response functions.
• The number of Schlieren and Shadowgraphy images.
• The number of extra photon energies in the workspace.
• The filepaths for the filter response functions.
• The photon energies of the extra photon energies.
• The image data, in order of the columns:
  • the horizontal and vertical coordinates of the center of the pixel in cm
  • the unfiltered intensity at the pixel in erg/cm2/s.
  • the number of the line of sight.
  • the intensity at the pixel for the FFC filtered image(s), if any, in ergs/cm2/s.
  • the intensity at the pixel for the XRD filtered image(s), if any, in ergs/cm2/s.
  • the integral of the areal mass along the line of sight in g/cm2
  • the optical depth at the extra photon energies
  • the intensity at the pixel of the extra photon energies in ergs/cm2/ster/eV/s.
  • the intensity at the pixel of the Schlieren images.
  • the intensity at the pixel of the Shadowgraphy images.

Simulation properties file - *.sim

Contains:

• The simulation time.
• The number of XRD filters
• The XRD voltage (in V) for each XRD filter.

Space integrated spectral file - *.sis

The first column is the photon energy in eV, the second is the space integrated intensity at the detector in erg/cm2/eV.

Spatially resolved spectral files - *.srh, *.srv

The horizontally (.srh) and vertically (.srv) resolved intensity at the detector. The three columns in the file are:

• The photon energy in eV
• The horizontal (srh) or vertical (srv) position of the pixel in cm.
• The intensity at the pixel in erg/cm2/eV

Optical depth iso-surfaces file - *.ods

Contains data locating the depth of surfaces of the optical depths entered in the workspace. These data are not yet displayed by Visualizer. The columns are:

• The x and y coordinates of the detector pixel for the line of sight.
• The (x,y,z) coordinates of the start of the line of sight
• The (x,y,z) coordinates of the end of the line of sight
• The number of the line of sight
• The fractional depth of the optical depth iso-surface for each value of the optical depth and each extra photon energy.

LOS output file - *.ilo

Written during drilldown. Equivalent to the .log file produced during the original simulation

Populations file - *.pop

Only written for a non-LTE calculation. Contains the populations for each atomic level (or group of levels if population collapsing is used) for each zone.

Zone intensity file - *.zdi

Contains the intensity at each detector pixel from each plasma zone as well as the space integrated intensity from each zone.

Zone specific data file - *.zdt

Contains several plasma variable values and the populations and ionization fractions for a specific zone.
