How can I use energyplus weather converter to split global radiation in to direct normal and diffuse horizontal radiation

edit

Thanks a lot for your answer.

Hi,

I try to read about weather converter in the Auxiliary Programs.

As @AmyLee said, I did not understand how EnergyPlus weather Converter can split the Global solar Input, it is not very helpful.

Maybe some more explaination will be helpful?

Thank you,

In the "def" file, the DataElements field specifies the contents of each column of the data file starting with column 1. If the weather data file only has global solar data, then this list will include only GloHorzRad (or Global Horizontal Radiation, long and short names are valid). When this data is processed, the Weather Converter will automatically split this into direct and diffuse.

Thanks Michael for your update.

I tried to delete direct and diffuse radiation in "DataElements", "DataUnits" and "DataConversionFactors" lists in def template file. But it will report errors when trying to deal with CSV weather file with direct and diffuse radiation column deleted. The only way I find can be successfully operating is to delete all the direct and diffuse radiation data in CSV while keep them in the def file lists.

BTW. it will be very helpful to have a checking list(like e+ error file) if there are errors occurred in the weather converting and the whole process crushed.

Hi Amy, I would really like to know how you made it work. I tried both your suggestions and it does not work for me. Could you provide your .def and .cst files that succeeded ? Thanks so much! @michael : I tried what you said and it does not work for me. Any other insights on that matter? I really think the documentation is lacking explanations on that matter ! Thanks everybody!
