2D implementation of Kinetic-diffusion Monte Carlo in Eiron
Oskar Lappi, Emil Løvbak, Thijs Steel +1
Particle-based kinetic Monte Carlo simulations of neutral particles is one of the major computational bottlenecks in tokamak scrape-off layer simulations. This computational cost c…

Analysis of kinetic-diffusion Monte Carlo simulation and source term estimation scheme in nuclear fusion applications
Zhirui Tang, Julian Koellermeier, Emil Løvbak +1
In plasma edge simulations, the behavior of neutral particles is often described by a Boltzmann--BGK equation. Solving this kinetic equation and estimating the moments of its solut…

Numerical analysis of fluid estimation for source terms in neutral particles simulation
Zhirui Tang, Emil Løvbak, Julian Koellermeier +1
In plasma edge simulations, kinetic Monte Carlo (MC) is often used to simulate neutral particles and estimate source terms. For large-sized reactors, like ITER and DEMO, high parti…
