Attributes Documentation

T_e

The electron temperature over the course of the simulation in kelvin.

The index of this array corresponds to the time step.

abundances

The relative elemental abundances of the elements modeled in this simulation.

The keys are the atomic symbols and the values are a float representing that element’s elemental abundance.

elements

The elements modeled by this simulation.

ionic_fractions

Return the ionic fractions over the course of the simulation.

The keys of this dictionary are atomic symbols. The values are 2D arrays where the first index refers to the time step and the second index refers to the integer charge.

last_step

The time index of the last step.

max_steps

The maximum number of time steps allowed for this simulation.

n_e

The electron number density over the course of the simulation in units of number density.

The index of this array corresponds to the time step.

n_elem

The number densities of each element over the course of the simulation.

The keys of n_elem are atomic symbols. The values are 1D arrays with units of number density where the index refers to the time step.

nstates

Return the dictionary containing atomic symbols as keys and the number of ionic species for the corresponding element as the value.

number_densities

Return the number densities over the course of the simulation.

The keys of number_densities are atomic symbols. The values are 2D arrays with units of number density where the first index refers to the time step and the second index is the integer charge.

time

The time for each time step over the course of the simulation in units of seconds.
