[yt-users] Projection of 2D cylindrical FLASH data

[Michael Zingale]

to be clear here, what Flash calls cylindrical is 2-d axisymmetric, r-z.
If I understand what you are asking, you basically want to still have a 2-d
plot where each cell is the integral over an annular region as if that cell
were rotated about the symmetry axis -- is that right?
