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:

During Sizing: 0 Warning; 0 Severe Errors. *** EnergyPlus Terminated--Fatal Error Detected. 1 Warning; 68 Severe Errors; Elapsed Time=00hr 00min 1.32sec

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

You haven't define a construction for your surface.

You didn't tag your question properly, did you? I'm thinking that you're using OpenStudio. See my answer to the same exact problem here for common causes.

If you're using EnergyPlus only, just find this surface and make sure you're filled something in the "Construction Name" field.

Relating to the comment you posted as an answer: read the post I linked... You might not have applied the construction set to your building, or it might be an adiabatic surface... Just investigate a bit.
