The Attila® Software Suite Productivity enhancing solutions for radiation transport simulations Design with Atti la and verify with MCNP*, all through one graphical user interface (GUI). Key features > Direct CAD integration > Automated, efficient variance reduction for MCNP > User-friendly GUI > Fast and accurate deterministic solver Attila4MC™ Software Attila4MC improves analysis productivity by providing MCNP users with CAD integration, automated variance reduction, and a user-friendly interface. Through the intuitive Attila4MC GUI, analysts can now import geometry directly from CAD and leverage MCNP’s new unstructured mesh functionality. Attila4MC’s state-of-the-art deterministic solver automatically generates optimized weight windows with a minimal amount of user interaction, bypassing inefficient time-intensive manual variance reduction. Through Attila4MC’s GUI, most MCNP calculations can be set up entirely without editing an input deck, simplifying analysis and verification. SpaceClaim® is offered as an integrated option with Att ila4MC, providing users with the full power of direct CAD modeling at their fingertips. With SpaceClaim, analysts can create, import, manipulate, and repair complex geometry in ways previously only possible by fulltime dedicated CAD experts. Attila Software Attila is a state-of-the-art software system providing fast and accurate solutions to demanding radiation transport applications. Attila leverages an advanced deterministic Boltzmann Transport Equation solver with an intuitive GUI and CAD integration, enabling users to rapidly and reliably perform complex calculations. Attila is ideally suited for applications dominated by large at enuations, such as radiation shielding. At ila calculates the solution everywhere, not just at predefined tally locations. By providing both visual and quantitative output options, At ila provides analysts with insightful data needed for informed design decisions. For design verification, Attila includes the full functionality of Attila4MC. With Attila, users can now easily obtain solutions from two independent first principle solvers, Att ila and MCNP, with the effort of only one. Attila is ideal for design, providing the full solution space for users to identify the location of critical areas and hot spots. MCNP is ideal for verification, providing an independent stochastic check of the deterministic Attila solution. *MCNP is a trademark of Los Alamos National Security, LLC.
