Neural Operator Surrogates for Two-Dimensional Neutron Flux Estimation
Japan K. Patel, Barry D. Ganapol, Anthony Magliari +2
This work extends our one-dimensional single-sweep neural-operator studies to two dimensions. We consider one-group transport with isotropic scattering. As in the one-dimensional w…
MAAS-SFRThelper: An Integrated ESAPI Plugin for Structure Generation, Optimization, and Evaluation of Spatially Fractionated Radiation Therapy
Japan K. Patel, Todd A. Wareing, Tenzin Kunkyab +13
Spatially fractionated radiation therapy (SFRT) planning requires three coordinated tasks: generation of high-dose sphere structures, position-aware optimization, and peak-valley d…
Evolutionary Discovery of Sequence Acceleration Methods for Slab Geometry Neutron Transport
Japan K. Patel, Barry D. Ganapol, Anthony Magliari +2
We present a genetic programming approach to automatically discover convergence acceleration methods for discrete ordinates solutions of neutron transport problems in slab geometry…
Assessing AI-Enhanced Single-Sweep Approximations for Problems with Forward-Peaked Scattering in Slab Geometry
Japan K. Patel, Matthew C. Schmidt, Anthony Magliari +1
While the Boltzmann transport equation can accurately model transport problems with highly forward-peaked scattering, obtaining its solution can become arbitrarily slow due to near…
