This parameter has to be used together with AspectRatio. If it is defined to a value f, while AspectRatio is defined to a value h_0, then the disk aspect ratio is defined everywhere by:

\frac Hr = h_0\cdot r^f

FlaringIndex defaults to 0, which means a uniform disk aspect ratio or, differently said, a local disk thickness proportional to the radius (“flat” disk).
