After the simulation is over or EnergyPlus encounters an error, the DOS shell will close and the focus will go back to the EP-Launch programme. A status window will open and show the number of warnings and errors along with time elapsed. If you have entered the data correctly and installation of EnergyPlus is correct you will not get any errors. Press OK.
If there are errors press the “ERR: button in the “Quick Open Panel for Single Simulation” window. This is a small window below the EP-Launch window. The error file will be opened in Notepad. Try to understand the error and fix it. If the problem still persists, mail me your IDF file at energyplustutorial[at]gmail.com
