openmc-source-plotter 0.1.0

Extract data and create plots of OpenMC particle sources

A Python package for plotting the locations, directions or energy distributions of OpenMC source particles

Installation

pip install openmc_source_plotter

temporary fix For fixed source sources it is currently necessary to use openmc version 0.11 and also to point the openmc_exec path to the openmc executable This can be installed with:

conda install -c conda-forge openmc=0.11

Features

The package provides functions to:

• create the initial_source.h5 for a give openmc.source
• extract the locations, directions and energy of particles
• provides convenient plotting functions for
  • direction
  • energy
  • location

Example plots

Plot of energy distribution of the source

import openmc_source_plotter as osp
import openmc
import numpy as np

# initialises a new source object
my_source = openmc.Source()

# sets the energy distribution to a Muir distribution neutrons for DT fusion neutrons
my_source.energy = openmc.stats.Muir(e0=14080000.0, m_rat=5.0, kt=20000.0)

# plots the particle energy distribution
plot = osp.plot_source_energy(
    source=my_source,
    number_of_particles=2000,
    energy_bins=np.linspace(0, 20e6, 100),
    openmc_exec="/home/jshim/miniconda3/envs/openmc_0_11_0/bin/openmc",
)

plot.show()

import openmc_source_plotter as osp
import openmc

# initializes a new source object
my_source = openmc.Source()

# sets the direction to isotropic
my_source.angle = openmc.stats.Isotropic()

# plots the particle energy distribution
plot = osp.plot_source_direction(
    source=my_source,
    number_of_particles=100,
    openmc_exec="/home/jshim/miniconda3/envs/openmc_0_11_0/bin/openmc",
)

plot.show()
