[Users] More Bizarre Scheduling Behavior in a Carpet Run (Bug?!)

Not sure if this is what happens to you but I got caught by this once:

If you are scheduling everything in GLOBAL (which is the same as
GLOBAL-LATE in ANALYSIS) then your OUTPUT will be incorrect since OUTPUT
is happening in LEVEL mode thus refinement level 3 is output before the
GLOBAL routine (which runs along with level 0) is executed. So your
output is wrong but the data that the simulation sees would actually
correct. An easy fix is to use GLOBAL-EARLY instead of GLOBAL.

So I would add print statements or the like (or Ian's suggestion of
calling OutputVarAsByMethod) to get output directly out of the
loop-local routine (actually it may have to be loop-level though I am
not sure).

Yours,
Roland
