MaCaw is a MOOSE-based application that enables domain-decomposed neutral particle transport calculations in MOOSE. It leverages the ray tracing MOOSE module for unstructured mesh tracking and OpenMC for collision physics, handling material definitions, and tallying quantities.

macaw's Introduction

MaCaw

MaCaw is a MOOSE-based Monte Carlo neutral particle transport code. It is designed to leverage the MOOSE ray tracing module for parallel scalability and OpenMC physics routines for reduced development cost and flexibility.

To build MaCaw:

Build OpenMC

git submodule init openmc git submodule update cd openmc mkdir build cd build cmake .. make -j 56 cd ../..

Build MaCaw

make -j 56

macaw's Issues

RNG seed types (unsigned long) are not represented exactly in ray auxiliary data

Reason

Example of seeds
seeds 3009189780765489792 5497575982607593661 7985962184449697530
The largest number we can keep exactly in a double auxData: 9007199254740993

Rounding them is not great. the properties of LCG are lost

Impact

Loosing some pseudo randomness

Fix is easy, just keep the error in another auxData and reconstruct the seed with 2 auxData
