September 2025 News

• A new tutorial for coupling OpenMC to the MOOSE subchannel module is now available.

• Per-cell density feedback has been added to both OpenMC and Cardinal:

  • Models requiring detailed density feedback no longer need unique materials per-cell, resulting in an improved quality of life for model preparation and a performance improvement during particle transport;

  • The MoabSkinner no longer adds unique materials for material+density bins.
