|---|---|---|---|---|---|---|---|
| Figure-1 | Wall-grid Figure-1 | Figure 1: A typical low- resolution JOREK grid with X-point. The domain bound- aries are defined by flux sur- faces in the SOL and the pri- vate regions, and by straight lines for the divertor targets. | 1 | CF/18/145 | Download | ||
| Figure-2a | Wall grid Figure-2a | Figure 2: (a) Magnetic flux contours (blue) for a Super-X configuration of the MAST-U device. The connected double-null separatrix contour is shown in red, the first-wall in green, and the PF-coils in yellow. | 0 | CF/18/146 | Download | ||
| Wall grid Figure-2b | Figure 2: (b) The initial rectangular grid on which the JOREK Grad-Shafranov equilibrium is solved, to obtain a flux-map consistent with ballooning unstable pre-ELM pressure profiles. For this Grad-Shafranov equilibrium, the boundary condition is the flux taken from the input equilibrium (a). This initial rectangular grid is defined inside the first-wall, to avoid the necessity of taking PF-coil currents into account for the Grad-Shafranov equilibrium. | 0 | CF/18/148 | Download | |||
| Wall grid Figure-2c | Figure 2: (c) The initial flux-aligned grid contained inside the first wall. This is the grid which can be extended. Note that a low-resolution grid is shown here for visual purpose. | 0 | CF/18/149 | Download | |||
| Wall grid Figure-3 | Figure 3: An example of successive grid patches applied between the flux-aligned X-point grid and the wall. Grid extension patches need to be quasi-quadrangles, but do not need to have linear sides. The user specifies the sides of the patch (red lines) using a set of input points (red points). The grid generator then automatically extends the grid between the grid side and the wall side (blue lines). | 0 | CF/18/150 | Download | |||

| Wall grid Figure-5 | Figure 5: (a) The direction of Mach-1 boundary conditions is determined by the direction of field lines going in/out of the domain boundary, which can change along the wall, (b) The change in direction of the Mach-1 boundary condition can occur within a few elements. | 0 | CF/18/154 | Download | |||
| Wall Grid Figure-6 | Figure 6: (a) The parallel heat-flux amplitude in a JET-ILW ELM simulation, (b) The electron temperature Te [eV] on the wall during an ELM simulation in JET-ILW. | 0 | CF/18/155 | Download | |||
| Wall Grid Figure-7 | Figure 7: A simulation of ELM filaments using the neutrals density model with divertor reflection of neutrals. Electron density (left) and neutrals density (right) are shown in the divertor region. Both quantities are normalised to the central ne value: 0.65 × 1020m?3. | 0 | CF/18/156 | Download | |||
