[yt-users] problem accessing EOSCriticalDensity parameter (enzo)

[David Collins]

I think yt only knows about certain parameters initially, and for
others you need to tell it how to parse.  I have things like this in
my plugins file:

from yt.frontends.enzo.definitions import parameterDict
parameterDict['WhatDoesABoatDo'] = float

which then tells yt what type of variable 'WhatDoesABoatDo' should be parsed as.
