## Enforcing conservation at Monte Carlo level in a coupled Finite Volume - Monte Carlo simulation KU Leuven

Plasma edge simulations generally require coupling a finite volume (FV) fluid plasma discretization with a kinetic neutral Monte Carlo (MC) model. From the MC neutral simulation, source terms are estimated and inserted into the FV plasma simulation, transferring MC stochasticity to the FV simulation. While the FV simulation is based on the physical principle of conservation, most common MC source term estimators do not strictly conserve mass, ...
