JOREK Physics Models

Reduced MHD:

model 600 is the workhorse for reduced MHD as it allows users to combine the different physics ($v_\parallel$, separate $T_e$ and $T_i$, fluid neutrals, fluid impurities, …) they wish to keep in their simulations at compile time. The variables that are always present in model 600 are:

Variable Symbol variable number
Poloidal magnetic flux: $\psi$ 1
Velocity stream function: $u$ 2
Toroidal current density: $zj$ 3
Vorticity: $\omega$ 4
Mass density: $\rho$ 5
Temperature: $T$ or $T_i$ 6

When $v_\parallel$ is used, it is always var_vpar=7.

For model 600, the variable numbers are assigned at compile time.

In addition to model 600, there are older, legacy, reduced MHD models shown below. However, new developments are not necessarily included in these models and, as such, users are suggested to use model 600.
