Hello,

I tried to run GenOpt (example file) but I found a error sign on the left side of the picture...

1.My question is how can i run GenOpt and see the graph?? ( the error sign!!)

2.I just copied

Parameter{
Name = w;
Ini = 1.5; Step = 0.05;
Min = 1; Max = 2;
Type = CONTINUOUS;}
Function{
Name = h; Function = "multiply( %w%, 0.5 )";}

this one in the command( i just followed tutorial) is it okay just copy and paste in comand file?

3.And this

ObjectiveFunctionLocation{

    Name1 = E_tot; 
    Function1 = "add( %E_heat%, %E_cool% )";

     Name2 = E_heat; 
     Delimiter2 = "Eheat=";

     Name3 = E_cool;
     Delimiter3 = "Ecool=";

    Name4 = height; 
    Function4 = %h%;
    }

I also copied this one in optWinXP file?

Thanks!

Do you actually have singleZonePuchAir.idfUSA_IL_Chiaco-OHare_TMY2.epw and RunEPlusPArallel.bat in the specified folder? also, did you check you're using the right E+ version?

Yes! I put all files in the same folder! :( What's wrong with me?! Thanks!!!

What E+ version do you have installed, and where?

It seems GenOpt is trying to run a very old version of E+, 3.1.0.

I'm assuming you are trying to run the example file in GenOpt\example\energyplus\3_1_0\GPSHookeJeeves

If you open RunEPlusParallel.bat, you'll see the path to E+ is hardcoded:

set program_path=C:\Program Files\EnergyPlusV3-1-0\

Unless you have E+ 3.1.0 installed in the above directory (which is extremely unlikely), it can't work!

Update

Considering there was a similar question asked, I've put together a tutorial on how to run GenOpt. Refer to my answer here or my Github directly

Besides Jullien's critical note (to update the hard coded path) you have to update the idf models of the GenOpt tutorial as well to match the E+ version that you are currently running. As of now (Aug 2015) in the GenOpt download the idf files under the latest folder named 'energyplus7_0_0' need to be updated to whatever version of E+ you are running. Update the idf files by using the IDFVersionUpdater which is located under the 'PreProcess' folder of your main E+ installation folder. In my case I updated those idf files from version 7 to 7.1 to 7.2 to 8 to 8.1 up to finally 8.2 and did Jullien's hard code correction as well and the simulation run smoothly.
P.S. there is no '.bat' file at the 'energyplus7_0_0' folder therefore you can copy the one from 'energyplus5_0_0' folder.

Julien is right, it seems like the problem is your E+ path. Having gone through similar errors with GenOpt, I would also add that make sure that you have your variables marked in the template idf. This should not be a problem given that you are using the tutorial files.

One other common error I used to get with GenOpt was when the number of my algebraic calculations command file were more than a certain number. It seems as if GenOpt would terminate over a certain line of code in the command line and would not be able to complete all the addition/subtraction/multiplication etc. functions that I wanted.

Hi All,

I am actually facing the same issues with GenOpt.

The error that I am obtaining when I try to run the first tutorial (GenOpt\example\energyplus\7_0_0\GPSHookeJeeves) is as follows:

Assigning 4 threads for simulations. Initialize. java.lang.Exception:

Exception in executing the simulation program

Simulation working directory : 'C:\Users\SambuKS\Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp-genopt-run-1' Command string : 'cmd /C ""C:\Program Files (x86)\EnergyPlusV7-0-0\RunEPlus.bat" "singleZonePurchAir" "USA_IL_Chicago-OHare.Intl.AP.725300_TMY3""' Exception message:

Error in executing the simulation program Exit value of the simulation program: 1 Working directory : 'C:\Users\SambuKS\Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp-genopt-run-1'. Current command String : 'cmd /C ""C:\Program Files (x86)\EnergyPlusV7-0-0\RunEPlus.bat" "singleZonePurchAir" "USA_IL_Chicago-OHare.Intl.AP.725300_TMY3""'. Error stream of simulation program : The system cannot find the path specified.

GenOpt terminated with error.

See logfile for further information.

Looks like it is looking for Eplus.bat Version 7.....

I have updated the E+ version by using the IDFVersionUpdater. From v7 to v8.3 .
In addition, as there is no 'RuenEplusPaarallel.bat' file at the 'energyplus7_0_0' folder I copied one from 'energyplus5_0_0' folder.

-I have also considered to change the weather file versions to the latest ones from E+ v8.3.3.

Any suggestions???

Best Regards,

The error is not with GenOpt but with your command string. Try running your command string from command prompt while using C:\Users\SambuKS\Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp-genopt-run-1 as your current directory.

Thanks for your reply Gilbert, unfortunately that does not works.... See below:

C:\Users\SambuKS>Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp-ge nopt-run-1> The syntax of the command is incorrect. C:\Users\SambuKS>cd.. C:\Users>cd..

C:>\Users\SambuKS\Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp- genopt-run-1 '\Users\SambuKS\Documents\GenOpt\example\energyplus\7_0_0\GPSHookeJeeves\tmp-gen opt-run-1' is not recognized as an internal or external command, operable program or batch file
