[TRNSYS-users] TrnOpt, Is it Constrained or unconstrained optimisation technique

[George Kyriakarakos]

Dear Dr. Mohammad Abdunnabi,

 

You can set the technical constraints of the optimization as cost penalties
in the objective function to be minimized. We have done exactly what you
want in the below paper, so that I am not writing everything again here:

Subject: [TRNSYS-users] TrnOpt, Is it Constrained or unconstrained
optimisation technique

 

Dear Trnsys Users

 

Does any body can confirm to me that all techniques provided in TrnOpt
(genOpt) Trnsys component is unconstrained optimisation technique. this what
I believe. if so, Plz if there is any way to run the optimisation with the
the objective function as the cost function and to put constrains on the
SF(solar faction of the system)?

The second question is that I've observed when I used weather external file
by using Type 9a and radiation process Type 16i with the other components of
thermosyphon system to complete the system and the optimisation componet
TrnOpt there is an error although when I run it without the optimisation
componet it's working fine. the error I get is:

 

Exception in executing the simulation program

Current command String: 'C:\TRNSYS17\Exe\TRNEXE.EXE
"C:\TRNSYS17\optimization\GENOPT\SIMULATION\GenoptInputFile.DCK" /n /WAIT '.
Exception message: 

Error in executing the simulation program
Exit value of the simulation program: 1
Current command String              : 'C:\TRNSYS17\Exe\TRNEXE.EXE
"C:\TRNSYS17\optimization\GENOPT\SIMULATION\GenoptInputFile.DCK" /n /WAIT '.
Error stream of simulation program  : Simulation program did not return an
error stream.

GenOpt terminated with error.
See logfile for further information.



Does any body can help to identify the error, and also I didn't find the
Logfile (is it List file)?

 

any help will be highly appertiated.
