11 Feb 2021 // Check out the recently updated Publications section of our website! We’ve collected an extensive list of third-party technical reports and peer-reviewed publications, including radiation transport on unstructured mesh specific publications. We will be constantly updating this page; let us know if we’ve missed anything!

14 DEC 2020 // We are pleased to announce that we released Attila 10.2.0-beta3 on November 25th, 2020. Attila 10.2.0-beta3 introduces the new Linear Discontinuous Adaptive to Step (LDAS*) spatial discretization, applicable for CADIS and FW-CADIS calculations with Attila4MC. LDAS is a new proprietary adaptive spatial discretization scheme that eliminates the possibility of negative flux solutions, other than those resulting from negative scattering sources, while retaining high accuracy through thick shields. LDAS can produce an accurate and smooth weight windows file for MCNP®, improving solution convergence rates. Also included in 10.2.0-beta3 is the Reprise License Manager, which provides a server based floating license capability. Attila 10.2 is scheduled for release early 2021. *Patent pending

15 AUG 2020 // Welcome to our new website!

04 MAY 2020 // We are currently testing Attila 10.2.0-beta2, released on May 4th, 2020. This latest beta includes an updated mesher to improve robustness and parasolid compatibility. 

07 JAN 2020 // An “adjoint grid flux correction” capability was added into Attila 10.2.0-beta1 to smooth weight windows for problems with significant ray effects, substantially improving performance for CADIS and FW-CADIS calculations.
