M3D-C

M3D is a Multilevel, 3D, parallel, plasma simulation code developed by a multi-institution collaboration. It is suitable for performing linear and non-linear calculations of plasmas in toroidal topologies including tokamaks and stellarators. Ideal and resistive MHD models as well as a two-fluid model are implemented. Particle-fluid hybrid options are currently being updated for parallel architecture. Recent tokamak studies conducted with M3D have addressed such topics as high-beta disruptions; two-fluid effects on internal modes; Toroidicity-induced Alfven Eigenmodes (TAE modes) (using a hybrid model); pellet injection; and the formation of current holes in discharges with off-axis current drive.
