EMC3-EIRENE is a state-of-the-art computational tool that combines the EMC3 (Edge Monte Carlo 3D) code with the EIRENE code to simulate plasma fluid and kinetic neutral edge transport in non-axisymmetric configurations. Developed for the study of stellarator and tokamak configurations, the code can model the full torus plasma and impurity transport, including the effects of 3D fields, such as resonant | EMC3-EIRENE is a state-of-the-art computational tool that combines the EMC3 (Edge Monte Carlo 3D) code with the [[EIRENE]] code to simulate plasma fluid and kinetic neutral edge transport in non-axisymmetric configurations.

EMC3 is a 3D plasma fluid code that solves a set of reduced Braginskii fluid equations for particles, parallel momentum, and energies for electrons and ions. The code models parallel electron and ion heat conductivity using classical assumptions. Perpendicular transport is determined by coefficients for anomalous particle transport (<math>D_\bot</math>) and anomalous electron and ion heat transport (<math>\chi_\bot</math>), which are free model parameters. EIRENE is a kinetic edge transport code that solves the transport equations for neutral atoms and molecules, accounting for collisional processes. The code calculates ionization sources, momentum sources/losses, and energy sources/losses due to atomic/molecular processes, such as charge exchange and ionization. EMC3-EIRENE models impurity transport using a fluid approach, causing energy losses to the main plasma through excitation and ionization. The trace fluid approach assumes that impurities only cause small density perturbations and impacts the main plasma species through ionization and excitation via an energy loss term in the energy balance equation. | EMC3 is a 3D plasma fluid code that solves a set of reduced Braginskii fluid equations for particles, parallel momentum, and energies for electrons and ions.
