Website Updates
I have fixed LaTeX display on the site and re-added the lightbox effect to images. From now on, clicking on most images will open them in a separate display, and clicking on the left/right side of that display will move to the previous/next image in the image set.
Boundary Transition
Density after one orbit
The artifact that appears at the grid boundary is still present in high-resolution when $\text{zxc}_i(\text{imax}) < \text{zxc}_o(1)$.
I will upload low-resolution results later today.
Density on the equatorial plane. The spiral transitions smoothly across the boundary, the right-hand side of the boundary is visually noticeable.
Density on the equatorial plane. Overlay of the grid boundary (dashed-cyan).
Density Jump
Density on either side of the artifact. As the artifact moves outward the jump in density grows until the artifact combines with the spirals.

Pressure after one orbit
Pressure in the equatorial plane. The artifact is not noticeable on the pressure scale.

Isosurface showing the discontinuity
A discontinuity is present when switching between the inner grid (blue) and outer grid (orange). This discontenuity does not seem to impact structure, however.
Full Isosurface. There are large gaps in the pressure isosurface when transitioning from the inner to the outer grid.
Clipped Isosurface. A better view of the gaps on either side of the dense equatorial plane.
Interior View. It is difficult to get a good shot, but the surface seems minimally effected desipite the gaps.
Further Investigation
The following images are from a completed run with slightly different parameters.
Density viewed along the equatorial plane. The same spiral shock feature shows up in this run.
Density viewed along the polar axis, the grid boundary can be seen fairly easily here.
Velocity (negative only, $\geq 0$ is red), viewed at the same angle as above.
Velocity (negative only, $\geq 0$ is red), viewed at the same angle as above.
Velocity (negative only, $\geq 0$ is red), viewed at the same angle as above. Inner grid has been removed.
To Do:
- print inner boundary in EnSight format, make sure it matches up with both the inner and outer grid
- output forces on each grid, plot as above
- if nothing is discovered, put together detailed explanation, EnSight files for John
