:index:`ERESTART`
---------------------------

An alternative method of restarting PFLOTRAN is to reload an Eclipse format restart file.

If present, ERESTART must be defined within :ref:`SIMULATION<simulation_card_sec>`.

ERESTART is used to restart a simulation from a given time. However, in the
case of ERESTART the solution is loaded from an Eclipse restart file, which may have been
written out by a Pflotran base run using the :ref:`eclipse output keywords <eclipse_files_sec>` keywords.

To reload from a unified Eclipse output file such as base.UNRST at 1000 days, use: ::

  ERESTART base 1000 d

To reload from an Eclipse multiple file called base.X0014, use: ::

  ERESTART base.X0014 1000 d
  
If you are not certain which multiple restart file contains the required time, specify: ::

  ERESTART base.X0000 1000 d

when the required time is not found on the nominated file, Pflotran will sweep through the files looking for the required time.
