I use this example from eppy documentation to run a simulation:

iddfile = "/usr/local/EnergyPlus-8-9-0/Energy+.idd"
IDF.setiddname(iddfile)

idfname = "/usr/local/EnergyPlus-8-9-0/ExampleFiles/BasicsFiles/Exercise1A.idf"
epwfile = "/usr/local/EnergyPlus-8-9-0/WeatherData/USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw"
idf = IDF(idfname, epwfile)
idf.run()

The document says that I should get an output like:

Processing Data Dictionary
Processing Input File
Initializing Simulation
Reporting Surfaces

Initializing New Environment Parameters
Warming up {1}
Warming up {2}
Warming up {3}

,however, I get nothing in the python. Only I see these new files in the directory that I run the python script: eplusout.audit eplusout.bnd eplusout.dxf eplusout.eio eplusout.end eplusout.err eplusout.eso eplusout.mdd eplusout.mtd eplusout.mtr eplusout.rdd eplusout.shd. These files include a lot different outputs, but the point is that I could not find any standard way of reading these files through eppy. In the documentation, there is a section Reading outputs from E+ which explains how one can use htmlreader to extract the output of E+ simulations. However, there is no html file among the generated files. I can read those files manually through f.read() function in python, but I thought probably I am missing a point and there should a way to get the output of the idf.run() directly in python. I would appreciate any help and comment.

Thanks, Afshin

Thanks for the explanations. I'll open a ticket in eppy issues.

When in Ubuntu, I call from eppy import ex_inits, I am getting:

About the function, I am kind of confused. let me re-paraphrase it, does E+ write the outputs in the html file or whatev

I added the objects using: idf.idfobjects['OUTPUTCONTROL:TABLE:STYLE'] = 'HTML; !- Column Separator'

I added the objects using: idf.idfobjects['OUTPUTCONTROL:TABLE:STYLE'] = 'HTML; !- Column Separator'

Additionally, is there any way to get a given output in return of calling idf.run()? not by reading some result file,

@santoshphilip Thanks for the suggestion. I tried newobject = idf.newidfobject("OutputControl".upper()), but it gives me

I have same problem. I was wondering is it any way to get some output as return of the IDF.run() than reading the text f
