Thanks for your helping.

Somewhere in your input file (IDF) there is a Material object where the first input field for Name is blank. This can be inferred from the specific error line copied below.

** Severe  ** <root>[Material] - Object name is required and cannot be blank or whitespace

Your Material object might look something like below, if you are editing the IDF in a text editor or IDF Editor that comes with EnergyPlus:

  ,                 ! Material Name (this is an example of a blank input field)
  Rough,        ! Roughness
  0.1014984,  ! Thickness {m}
  1.245296,    ! Conductivity {W/M*K}
  2082.400,    ! Density {Kg/M**3}
  920.4800,    ! Specific Heat {J/Kg*K}
  0.9000000,   ! Thermal Absorptance
  0.9300000,   ! Solar Absorptance
  0.9300000;   ! Visible Absorptance

Thank you, I've solved the problem. It was an accent in the definition of one material. Now the model works properly.
