RE: [EnergyPlus_Support] RVI or MVI files?

I have looked at your .rvi and the basekue.IDF.

Your .rvi will not work for EPlus .IDF or .ESO.

If it works or JEPlus, it will be fine.

Dr.Yi,

This is a specific .rvi for Je+, and does work- all that is changed is the variables to match the variables in the IDF used to create the je+ "Jobs"

jE+ creates a new simulation for each of the jobs, and all get the same intermediate file names.

I am thinking you are referring to the way e+ tends to work without jE+

So this simple .rvi would work for je+ with just the changed variable names, all variables for je+ would need to be for annual values, and this will create the csv file with all of the jobs output values in one file.

I have attached the full jE+ files I last used with this .rvi for further example.

Best regards-

Do not be offended, if you do not like me to add comments to your remarks.

The topic came up in the forum not long ago. Your .rvi in the current form may not work off-line as a post processor input.

There are sample batch files written by the EPlus experts in the past to list variables floor by floor, zone by zone, or by different classes using the same ESO after a long simulation run.

I just use the attached file , and change the variables to match the job.(it took me a while to figure it out from the IO, but it is actually very simple so I am sharing)

It contains this info:

eplusout.eso
eplusout.csv
Heating:DistrictHeating
Cooling:DistrictCooling
0

I have not tried your .rvi file. However, there are a number of problems.

"eplusout" is the name of the file during simulation. It is not available after the simulation.

For the above .rvi file to work, it must be present in the same directory as the user IDF file and have the same file name. The EPlus simulation batch file will test for the present of this file and rename it to in.rvi in the temp directory. If in.rvi is available at the end of simulation, the simulation would use this file to format the .csv file. If not, the whole .eso file would be sent to the .csv file. (up to default max of 250 columns) This is the function of the ReadVarsESO.exe.

If you do not have the variables spedified in the IDF, there will be no output. If the names are not correct in the rvi, there will be no output. The rvaudit will provide further information.

Heating:DistricHeating may not be the name of a valid variable. Therefore, the .rvi may not work. I usually have the OD drybulb as the first variable. Timestep size should be specified.

To use the .rvi as a post processor to customize the display columns using the ESO file with the IDF file name. The first eplusout.eso should be replaced with IDFfn.ESO. The second file hame should be the output file name say, DistrictHC.csv.

You can have many .rvi files for Windos heat gain of all or selected zones, Zone mean temperature only for one floor, etc. The .rvi files can be prepared and run in a batch file from one ESO.

The .RVI file may be resued for different projects, if you rename the IDFfn.eso to eplusout .eso or any other fixed name in your user file.

To explain:

eplusout.eso, this is what energy plus writes output to- the title is for the temp file energy plus produces for every run, in the temp directory before the last clean up section. The name in the user directory would be IDFfn.eso.

eplusout.csv is what format you want your output. (The name of the custom output file. You will not see the epusout.csv in the normal user directory, unless you do a post processing run..)

Variable names for each variable you want to report, and should have the desired reporting period specified.

0, this calls the end of file (To separate different sections of .rvi in one text file.)
Save your text as .rvi or .mvi (rvi for report variables, and mvi for meter variables)

Subject: [EnergyPlus_Support] RVI or MVI files?

Hello,

I'm using jEPlus for a parametric study, and it requires .rvi or .mvi files from Energy Plus to operate. I have already simulated the model in the Energy Plus but in the output folder there is neither a .rvi nor a .mvi file to be used for jEPlus. I was wondering if someone could tell me how to locate/generate these files.

Many thanks,
