Montecarlo and Envelope : not saving fd data?

Hi,

as the subject says. I have an ENV simulation set up from the ADEXL environment.

I created some function (using Calc) to plot a quantity of interest, based on the amplitude of some spectra out of the simulation.

This works O.K. for corners, however I tried a MC run and I get an 'eval err' in the Results pane. While chasing the problem, I found out that the MC run does not seem to include data in the 'envlp_fd' folder. Since the Calc function uses data from there, it cannot but fail.

Anybody had experience with MC and ENV? Is that something to 'expect' or am I missing a piece?

Cadence version : 6.1.5.500.11 (64b)

Note: I am ticking the 'save data to allow family plots' box in the MC options, although I would not really like to do so in the long run...
