Re: [TRNSYS-users] questions about TRNOPT

["Matt Duffy" <duffy@tess-inc.com>]

Dear Yin Hang,

Please make sure that you can first run the example (.\Optimizaiton\Example\Example.tpf) sucessfully in the TRNSYS Simulation Studio. If that runs ok, then implement the TRNOPT with the input (*.dck) file for that example as outlined in the tutorial (.\Optimization\Documentation\TrnOptv17.pdf). I see from your email below that you were able to do this, no? If you have problems and as the tutorial says, you will have to look in the *.lst or *.log file in the ".\Optimizaiton\GenOpt\Simulation" and/or ".\Optimizaiton\GenOpt\Configuration" directories.

The other issue is that you have to make sure that in the *.log file, the TRNOPT component Type583 needs to be loaded from the "TESSOptimizationLibrary_v17.01_Release.dll" and NOT any other former DLL.

Last, please make sure that you are using at least GenOpt 3 for TRNOPT v17.

Best regards,

Matt Duffy

Subject: [TRNSYS-users] questions about TRNOPT

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 optimizatio! n 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: Simulat! ion 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
