Hello,

I am adding a comment to an old thread posted by Lars in September 2009, attached bellow.
When I used a .inp file generated by eQuest in DOE2.2, I encountered the same problem as Lars explained.

In my case, the reason for the error was the "Variable Speed Drive FPLR" was not defined in the DOE2.2 library "BDLLIB.DAT". This library file is at "C:\doe22\exent" by default. There are several ways to solve this problem.

1) In the same directory as "BDLLIB.DAT", there are some libraries for eQuest such as "eQ_Lib.363.dat". When you run DOE2.2, select an eQuest library file with appropriate version instead of "BDLLIB.DAT".

2) Use a curve which is already defined in the DOE2.2 library "BDLLIB.DAT" such as "Fan-Pwr-fPLR-w/VFD". I plotted "Fan-Pwr-fPLR-w/VFD" in DOE2.2 library and "Variable Speed Drive FPLR" in eQuest library to see the difference. These curves are almost identical. However, as the comment in the library file says, "Fan-Pwr-fPLR-w/VFD" includes +0.05 to points to account for the VSD losses, and at each point, "Fan-Pwr-fPLR-w/VFD" curve is about 0.05 larger than "Variable Speed Drive FPLR" curve.

3) Copy the following portion of the definition of "Variable Speed Drive FPLR" to the library "BDLLIB.DAT".

$LIBRARY-ENTRY Variable Speed Drive FPLR CURVE-FIT Fan EIR-FPLR
$Any fan with Variable Speed Drive
TYPE = QUADRATIC
INPUT-TYPE = COEFFICIENTS
OUTPUT-MIN = 0.10
OUTPUT-MAX = 1
COEFFICIENTS = ( .219762, -0.874784, 1.652597 )

I tested only 1) and 2), but I think 3) would work. 1) would solve other incompatibility problems related to the definition in libraries. It would be helpful if anyone could tell me how to assign several different library files when you run DOE2.2.

I hope this information would save someone's time.

eQuesters & Brett,

Thanks for your help, Brett. The BDL file shows the following. It also showed the same error with or without quotes around the U-name in line 3017 and with or without the $ in line 3010. Evidently, eQuest is just not recognizing the parent system that I defined line lines 2994 - 3016.
Does anyone know why this would be - especially when, as explained in the original e-mail (below), I based this code on that generated by eQuest?
