Attila4MC provides MCNP® 6.2 and 6.3 users with a GUI based environment to set up, run, and visualize MCNP unstructured mesh solutions from complex CAD geometries.
In this workshop, the new "real-world" CAD workflow in Attila4MC will be demonstrated on a representative shielding example. This workflow enables users to work directly from dirty CAD assemblies with hundreds or thousands of parts, and with "transport insignificant" part interferences, mostly eliminating the need for time consuming CAD cleanup and simplification. An integral part of this workflow is the new Cottonwood Variance Reduction module, which performs CADIS and FW-CADIS variance reduction on complex models through an automatic arbitrary mesh refinement (AMR) deterministic solver. Cottonwood automatically generates the deterministic computational grid, and MCNP weight window grid definition based on a user supplied target half value layer (HVL).
The new Fornax activation module will also be demonstrated. Fornax provides MCNP users with a GUI driven workflow for shutdown dose rate (R2S method) and inventory calculations.
The second half of this workshop is hands-on, where attendees will set up, run, and visualize a deep penetration shielding model starting from CAD. Attendees wishing to run Attila4MC should bring a Windows 10 or 11 laptop with at least 12 GB of RAM. Attendees wishing to also run MCNP must have MCNP 6.2.0 or 6.3.0 installed. Attendees are invited to bring their own CAD models (Parasolid® or ACIS® formats preferable), as the last half hour will include an optional open workshop allowing users to work through their own models with help from Silver Fir Software instructors.
All attendees will receive a 1-month license of Attila4MC following the workshop. For any questions regarding the workshop, contact support@silverfirsoftware.com.
