Problem with output data - Junghun Lee - 10-15-2015
Hi.
I’m a new user of jEPlus. To practice the jEplus, I select the EnergyPlus example file, 5ZoneAirCooled.idf file and set the output variable ‘Zone Air System Sensible Cooling Rate’ in rvi format. The parameter search tag is @@people@@ and the range of variations are {1,5}.
However I am not able to get SimResults, but RunTimes and SimJobIndex files are fine.
Furthermore, the example projects in jeplus.org, UK Office Building Archetypal Models v8.1, also can not get the output data.
I’m attaching idf and rvi files that I calculated.
regards,
Lee

Hi Lee,
From v1.6 jEPlus collects rvi results with user-defined frequency, which is "annual" by default. Since the IDF model only produce "Timestep" output, jEPlus cannot get any annual data, therefore the SimResults.csv is empty. There are two ways to handle this issue: (1) change the reporting frequency of "Output:Variable,*,Zone Air System Sensible Cooling Rate" to "annual" in the IDF file; or (2) use the new RVX file to define RVI extraction and explicitly specify frequency to "Timestep". Below is an example RVX to use with your aaa.rvi. Copy and paste this to a file (e.g. my.rvx) and assign it to your project, jEPlus will then get your output data.
{
"notes" : "Some notes about this RVX",
"rvis" : [
{
"fileName" : "aaa.rvi",
"tableName" : "SimResults",
"frequency" : "TimeStep",
"usedInCalc" : true
}
],
"sqls" : [
],
"csvs" : [
],
"scripts" : [
],
"userVars" : [
],
"constraints" : [

"objectives" : [
]
}
