[TRNSYS-users] questions about TRNOPT

[Yin Hang]

Dear TRNSYS users,

Probably this question was already been asked, but I could
not find the answer. I hope someone could help me out with
my problem.
I want to use TRNOPT for a optimization problem. I use
TRNSYS 17 for my model, and I believe the TRNOPT is version
17. 
My model works fine in the simulation studio, although it
takes several warnings. But when the GENOPT starts, I
received an error message in the GENOPT screen:

"Assigning 2 threads for simulations.
Initialize.
Java.lang.Exception:

Exception in executing the simulation program

Simulation working directory:..
Command string:.

Error in executing the simulation program
Exit value of the simulation program: 1
Working directory: .
Current command String:.
Error stream of simulation program: Simulation program did
not return an error stream.

GENOPT terminated with error.
See logfile for future information.
"

Could someone tell me what does this error mean, or where
can I find more detailed information about this error? 
I run the example in genopt, and it works well. So I believe
there should be something wrong with my model rather than
the software itself.

Thanks.
Yin (Kathy) Hang
