The Q2D code is a 2D MHD code, which includes a neutral fluid and separate ion and electron temperatures. The equations contain source terms due to neutral beams, which are calculated using a 3D Monte Carlo code. Q2D has been benchmarked against the 1D transport code Q1D and is used to simulate the evolution of the C-2 and C-2U field reversed configuration experiments . Q2D simulations start from an initial equilibrium and transport coefficients are chosen to match the experimental data. C-2U is an upgrade of C-2, with more beam power and angled beam injection, which demonstrates plasma sustainment for 5+ ms. The simulations use the same transport coefficients for C-2 and C-2U, showing the formation of a steady state in C-2U, sustained by fast ion pressure and current drive.
