MCNPtools

This repo contains python modules and scripts that help managing MCNP simulations and outputs.

read MCTAL

To easily plot MCNP data the script scripts > TallyRead.py reads MCTAL files, and generates the directory mOut containing a file for each implemented MCNP tally. These files are called by their tally name and contain the results separated in 6 columns:

1. cell number
2. segment number
3. cosine value
4. energy value
5. tally output
6. tally error

These files are easily imported with numpy into a python script and subsequently plotted with matplotlib or other plotting libraries.

Use

The script generates the output directory in the same directory of the MCTAL file, to execute the script type:

./TallyRead.py ~/PATH/TO/MCTAL

NOTE: it is necessary to define the path of the input starting from the home (~) directory.

Jupyter

To install jupyter notebook please refer to the installation guide.

The Jupyter notebook example is in example > JupyterNotebook, in that directory there is an MCNP input file mcnp.inp and the MCTAL output file mcnp.inpm. This latter file was read by ./TallyRead.py into the example > JupyterNotebook > mOut > f2 file which can be easily used to plot data through the notebook. for more detail open the notebook.

examples

• WriteTally.py -> An example script that uses Gen.Tally module to write a surface current tally
• WriteSDEF.py -> An example script that uses Gen.SDEF modulte to write an MCNP SDEF source
• readMCTAL.sh -> Bash script that uses the python module mc-tools to extract tally data into separate files.

Requirements

• Python versione >= 2.7
• numpy
• matplotlib
• mc-tools
