Hi, Jia

Looked like you were using the Window "run" to execute the ReadVarsESO.exe.

If you only need to create one custom .csv for each simulatin, you can use a .rvi having the same name as the IDF file and place it in the same folder as the .IDF.

The EPlus batch file will look for it automatically, and rename it to in.rvi in the temp folder. After the simulation, it will for the in.rvi, if found, the custom .csi would be produced. If the in.rvi is not found, the full .csv would be produced.

The "eplusout" is the prefix for all the output files. It will be replaced by the input IDF filename and placing them in your user directory. "eplusout.eso" and "eplusout.csv" are the two file name in the temp directory during simulation..

The content of the .eso is controlled by the Report Variable entries in the IDF. Even if you supply a custom .rvi during simulation, full set of data values are in the .eso file. However, only 250 columns would be sent to the .csv. This number can ge increased.

When you want to create more customed .csv from one .eso file, remember that the .rvi passed on the command line should have the name of the .eso matches the one you wanted to use, and the second line is the custom .csv file should be different from any existing .csv file.

If you want to leave them as "eplusout.eso" and "eplusout.csv", simply creat a directory and open and save the .eso file with that name. Every time the data is extrated, change the .csv file before making another run of .rvi.

You can place C:\\EnergyPlusV7-1-0\\PostProcess\\ReadVarsESO.exe" project.rvi
in the desk top short-cut icon.   With "Start in" pointing to your directory where project.rvi and project.eso are in. Every time you click to excute that icon, it will go to the DOS screen and produce a project.csv file in the user directory..

If you use a batch file, then all the command can be in one text file with the full path of the directories. This will reduce typing mistakes, and build up a number of standard .rvi files for different purposes.

About two years ago, there were some examples in this forum by the experts to show how to use batch file to run .rvi file to split the data into groups of lloors, functions, etc.

Hi Dr.Li,

In my case, I need to convert several eso files to csv files, so I would like to manually run the command instead of using batch file. The .rvi file simply has two lines as shown below. I use the command: "C:\\EnergyPlusV7-1-0\\PostProcess\\ReadVarsESO.exe" project.rvi

project.eso
project csv

Thanks,

Jia

Thank you, Linda and Dr.Li. I will take a look and let you know.

If you cannot follow the DOS batch file syntax, send me the .rvi you have written, and I shall try to explain it to you.

Hello:

In my simulation, sometime readvarseso.exe does not run automatically to convert .eso to .csv file. I can use command "ReadVarsESO.exe" to convert "eplusout.eso" to "eplusout.csv".

My question is that how I can use "ReadVarsESO.exe" to convert "project.eso" to "project.csv", using a name other than "eplusout"?

Thanks,
