### 2.8.4 Restarting a Run

When the creation of a restart dump file is requested, the analysis can be restarted from the last converged timestep. This is useful when the run terminated unexpectedly or when the user wishes to modify some parameters during the analysis. To request the creation of a dump file, simply add the -dump flag on the command line. This will generate a dump file which then can be used to restart the analysis. You can specify an optional dump level, which sets how often the dump file is created, and an optional dump file name.
> febio -i input.feb -dump

With the optional arguments, the complete syntax would be:
>febio -i input.feb -dump=1 out.dmp

The dump level can set to 1 (= write dump file after each converged time step), or 2 (= write dump file after each completed step).
To restart an analysis, use the -r command line option. This option requires a filename as a parameter, and this name can be either the name of a dump file or the name of a restart input file. The latter case is a text file that allows the user to redefine some parameters when restarting the run. The format of this file is described in Chapter 5↓.
