Implementation of drift velocities and currents in SOLEDGE2D-EIRENE

Davide Galassi, Nicolas Mellet, Eric Serre

In order to improve cross-field transport description, drifts and currents have been implemented in SOLEDGE2D-EIRENE. The derivation of an equation for the electric potential is recalled. The resolution of current equation is tested in a simple slab case. ...

Convolution and iterative methods applied to low frequency waves in 3D configurations

Laurent Villard, Wilfred Anthony Cooper, Stephan Brunner, Nicolas Mellet

Kinetic effects have been implemented in the three-dimensional full-wave code LEMan. These allow modeling Landau damping as well as the Kinetic Alfvén Wave (KAW). Special attention has been taken on the exact computation of the parallel wave vector as it c ...

Integrated modelling of Ion Cyclotron Resonant Heating in toroidal system

Wilfred Anthony Cooper, Jonathan Graves, Stephan Brunner, Martin Jucker, Nicolas Mellet

An integrated model capable of self-consistent Ion Cyclotron Resonant Heating (ICRH) simulations has been developed. This model includes both full shaping and pressure effects, warm contributions to the dielectric tensor, pressure anisotropy and finite orb ...

The Dependence of the Damping Rate of Medium-n Toroidal Alfvén Eigenmodes on the Edge Plasma Elongation in JET

Ambrogio Fasoli, Duccio Testa, Patrick Blanchard, Theodoros Panis, Nicolas Mellet

This paper reports the first quantitative analysis of the measurements of the damping rate (gamma/omega) for stable Alfvén Eigenmodes (AEs) with toroidal mode number (n) in the range |n|=3-15 as function of the edge plasma elongation (kappa95). We find tha ...

Propagation and absorption of low frequency waves in two and three dimensional warm plasmas

Nicolas Mellet

In order to model a broader range of phenomena taking place in three-dimensional plasmas, the LEMan code has been extended to a warm formulation. As the wave propagation is strongly influenced by the parallel wave vector, special attention has been paid fo ...

Parallelization of the LEMan Code with MPI and OpenMP

Wilfred Anthony Cooper, Nicolas Mellet

The low-frequency wave propagation code LEMan has been parallelized. Due to large memory requirement but fast computation with the cold model, the parallelization is limited to a low number of processors. The specific block-tridiagonal structure of the mat ...
