This repository contains scripts intended for comparisons of DAG-OpenMC (OpenMC using DagMC geometry) to DAG-MCNP (MCNP using DagMC geometry).

For more information about these projects please see:

• OpenMC
• MCNP
• DagMC

NOTE: These models rely OpenMC's ENDFB-VIII.0 data found here

Retrieving the DAGMC Models

To run each model they should be downloaded from the following links and placed in their respective folders:

• Collimator
• Frascati Neutron Generator (FNG)
• Advanced Test Reactor (ATR)

The get_dagmc_models.sh script can be used to download these models and place them in the correct locations.

Running a comparison

1. Enter the directory of a model (e.g. FNG)
2. Run python run.py to run both versions of the geometry and compare the results

Use python run.py -h to see various options availble when performing the comparisons.
