thunderboltz.CrossSections

class thunderboltz.CrossSections(directory=None, input_path=None, read_cs_data=True, cs_dir_name='cross_sections', input_fname=None)

ThunderBoltz cross section set data type. Consists of a set of cross sections each with a file reference and a reaction table.

Parameters:

• directory (str) – The path to a ThunderBoltz simulation directory in which input files are to be written. Default is None.

• input_path (str) –

  The path to a set of ThunderBoltz input files from which input data can be read. The file structure should be something like:

  path/to/input_path
   |———indeck_file.in  <— The main ThunderBoltz indeck file.
   |———cross_sections  <— Cross section directory
   |   |———cs1.dat     <— ThunderBoltz-formatted cross section file.
   |   |———cs2.dat     <— ThunderBoltz-formatted cross section file.
   |   ...
   ...
  

• cs_dir_name (str) – The name of the cross section directory.

• input_fname (str) – The name of the main ThunderBoltz indeck file. Default is None, in which case the indeck will be searched for in input_path and must end with .in.

Attributes

cs_dir_name	Place for cs files in simulation dir
input_fname	Input deck filename default
table	The reaction table, with columns
data	Data tables for each cross section.
input_path	Input path to default input data

Methods

add_differential_model(rtype, name[, params])	Add a differential model to a certain type of process.
add_process(p)	Take a Process object and update the cross section data and cross section reaction table.
add_processes(ps)	Add multiple cross sections to the reaction table.
find_infile()	Look for indeck file in input_path.
from_LXCat(fname)	Load cross section data from an LXCat .txt file
get_deck()	Return the string formatted cross section table portion of the ThunderBoltz indeck.
plot_cs([ax, legend, vsig, thresholds])	Plot the cross sections models.
read(input_path[, read_cs_data])	Read ThunderBoltz cross section data from a directory with a single input file and a set of cross section files.
set_fixed_background([fixed])	Set all particle conserving processes to have the FixedParticle2 tag or not.
write([directory])	Write cross section files into the simulation cross section directory.
