After osm file simulation, there have 6 folders under the projectname/run, which are 0-null, 1-modeltoldf, 2-expandobject, 3-userscript, 4-energyplusprocess, 5-energyplus, what does the files in each folders' mean? e.g, there have a in.idf in 1-modeltoldf, and an out.idf in 4-energyplusprocess, what's difference between them, thanks!
