Unstructured Mesh Tools for Fusion Energy System Design
Mark S. Shephard, Jacob S. Merson, Onkar Sahni +6
The execution of accurate simulations of fusion energy systems requires the appropriate representation of critical component geometries as well as the coupling of complex fusion ph…
A Stochastic Conservative Field Transfer Method for Black-box Multiscale and Multiphysics Coupling
Abhiyan Paudel, Cameron W. Smith, Jacob S. Merson
This paper introduces a new method for performing field transfer operations in black-box coupling, when source discretization information is not available. This approach uses a sto…
PCMS: Parallel Coupler For Multimodel Simulations
Jacob S. Merson, Cameron W. Smith, Mark S. Shephard +5
This paper presents the Parallel Coupler for Multimodel Simulations (PCMS), a new GPU accelerated generalized coupling framework for coupling simulation codes on leadership class s…
GPU Acceleration of Monte Carlo Tallies on Unstructured Meshes in OpenMC with PUMI-Tally
Fuad Hasan, Cameron W. Smith, Mark S. Shephard +5
Unstructured mesh tallies are a bottleneck in Monte Carlo neutral particle transport simulations of fusion reactors. This paper introduces the PUMI-Tally library that takes advanta…
