Hi there,
@chris
I tried to run des_example in Dragonfly but I faced the following error:

Usage: uo_des build-sys-param [OPTIONS] SYS_PARAM_FILENAME SCENARIO_FILE
FEATURE_FILE [MODEL_TYPE]
Try ‘uo_des build-sys-param -h’ for help.
Error: Got unexpected extra argument (time_series)

I would appreciate it if you could kindly assist me to solve the challenge

Thank you very much for your time and assistance

Hey @behnammmohseni ,

It looks like you are using an older version of that sample file with a newer installation of Ladybug Tools. Because the DES workflows have been heavily refactored in the last few months, I recommend running the LB Versioner to make sure that you have the latest development version.

Then you should use the latest version of that sample file here on the dragonfly-grasshopper repo.

Also note that, to use the URBANopt DES workflows, you must have Docker Desktop installed and running on your system:

Note that Docker is free as long as you are not using it in the context of a large company for which you are working.

Hello @chris,

Hello,
I am a new user of dragonfly/urbanopt/modelica. I tried to run the DES example included in LadyBug and the simulation seemed to complete. However, when I check the DES results folder, I only see the “stdout.log” file, while the others are missing. The “stdout.log” file reads as follows:

true
true
true
“”
record SimulationResult
resultFile = “”,
simulationOptions = “startTime = 17280000.0, stopTime = 17366400.0, numberOfIntervals = 960, tolerance = 1e-06, method = ‘dassl’, fileNamePrefix = ‘des_modelica.Districts.DistrictEnergySystem’, options = ‘’, outputFormat = ‘mat’, variableFilter = ‘.*’, cflags = ‘’, simflags = ‘’”,
messages = “Failed to build model: des_modelica.Districts.DistrictEnergySystem”,
timeFrontend = 0.0,
timeBackend = 0.0,
timeSimCode = 0.0,
timeTemplates = 0.0,
timeCompile = 0.0,
timeSimulation = 0.0,
timeTotal = 0.0
end SimulationResult;
"[/var/lib/jenkins3/ws/LINUX_BUILDS/tmp.build/openmodelica-1.22.1/OMCompiler/Compiler/NFFrontEnd/NFCeval.mo:1089:9-1089:67:writable] Error: Internal error NFCeval.evalBinaryMul failed to evaluate ‘0.0 / 0.0 * 0.0025‘
"

Do you have any clues about what is wrong? I would really appreciate your guidance.

I am using:
LadyBug 1.8, Docker Hub, Buildings 12.1.0, OpenModelica 1.26 (nightly build)

Thanks.
