My simulation fails and I don't know why. Open Studio says : "Processing Input File **FATAL:IP: Errors occurred on processing IDF file. Preceding condition(s) cause termination".

The file epluspot.err has about 70 errors. These are the first:

Program Version,EnergyPlus, Version 8.5.0-c87e61b44b, YMD=2016.04.05 20:52,IDD_Version 8.5.0 *** IDF Context for following error/warning message: *** Note -- lines truncated at 300 characters, if necessary... *** 224 BuildingSurface:Detailed, *** indicated Name=Surface 1 *** Only last 3 lines before error line shown..... *** 225 Surface 1, !- Name *** 226 Floor, !- Surface Type *** 227 , !- Construction Name * Severe * IP: IDF line~227 Error detected in Object=BUILDINGSURFACE:DETAILED, name=SURFACE 1 * ~~~ * Field [Construction Name] is required but was blank *** IDF Context for following error/warning message: *** Note -- lines truncated at 300 characters, if necessary... *** 240 BuildingSurface:Detailed, *** indicated Name=Surface 2 *** Only last 3 lines before error line shown..... *** 241 Surface 2, !- Name *** 242 Wall, !- Surface Type *** 243 , !- Construction Name * Severe * IP: IDF line~243 Error detected in Object=BUILDINGSURFACE:DETAILED, name=SURFACE 2

and this is the final part:

I'm a novice in this program. How can I solve the problem?
