Some of the primary capabilities of the PROPACEOS code are listed below.
Computes equation-of-state (EOS) and opacity data for single-element or multi-element
plasmas.
Includes an easy-to-use graphical user interface for problem setup and viewing
results.
Includes on-line documentation, including direct access to Help pages from
widgets.
Computes EOS and opacity data for LTE
plasmas and several types of non-LTE plasmas. Non-LTE plasma include:
Optically thin plasmas (photoexcitation and photoionization are ignored in the calculation of atomic level populations)
Finite size plasmas (photoexcitation and photoionization are included in the calculation of atomic level populations using a plasma characteristic size)
Plasmas which include a hot electron component (which can alter inner-shell emission spectra via collisional excitation and ionization)
Supports the use of simple and custom grids for:
Temperature
Density
Plasma size
Update 3 parameters used to define a hot electron component
Photon energy
Separate grids can be used for the EOS and opacity calculations.
High density effects are accounted for by including an optional QEOS model.
Includes graphics package for visualizing results for:
Frequency-dependent opacities
Equation-of-state parameters
Includes the following atomic processes in collisional-radiative modeling:
Collisional ionization, recombination, excitation, and deexcitation
Photoionization and stimulated recombination
Photoexcitation and stimulated emission
Spontaneous decay
Radiative recombination
Dielectronic recombination, autoionization, and electron capture
Multipliers can be applied to the rate coefficients for the above processes.
Includes Doppler, natural (including autoionization contributions), and Stark
broadening in line profile modeling.
Utilizes ATBASE suite
of atomic codes for supplying:
Photoionization cross-sections
Oscillator strengths
Collisional ionization cross-sections
Collisional excitation cross-sections
Atomic level energies and transition energies
Dielectronic recombination, autoionization, and electron capture rates.
Incorporates NIST atomic level energies and oscillator strengths when
available.
Can be used to view previously calculated PROPACEOS data files or
SESAME files
