Suppose the python code Cosim.py
will be placed into the python
folder under the xmlpath = 'D:/bcvtb/examples/CosimRtest'
.
library(CosimR)
Step1: generate the .xml file
xmlpath = 'D:/bcvtb/examples/CosimRtest' copy_xml(xmlpath = xmlpath)
Step2: modify the .xml file
file.copy(from = system.file("extdata/Cosim.py", package = "CosimR"), to = paste0(xmlpath,'/python'), overwrite = TRUE) xmlroot<- modify_xml(xmlpath = xmlpath, timeStep = 15*60, beginTime = 3*24*3600, endTime = 4*24*3600, extractLength = 2, idf = paste0(xmlpath,'/SmOffPSZ.idf'), epw = 'D:/bcvtb/examples/ePlusWeather/USA_IL_Chicago-OHare.Intl.AP.725300_TMY3.epw', outname = 'eplusout', programname = 'python', programArgs = 'Cosim.py', workingDir = paste0(xmlpath,'/python'), cpp = FALSE)
Step3: save the .xml file
write_xml(rootnode = xmlroot, xmlpath = xmlpath, output = 'new.xml')
Step4: run the .xml file
run_Cosim(bcvtbpath = 'D:/bcvtb', xmlpath = xmlpath, output = 'new.xml')
Plotter block is not included in the .xml template file provided in the CosimR
package. If you want see the results in real time, add plotter block in BCVTB manually is a good choice.
