### 2.7.2 Output files

After running FEBio, two or three files are created: the log file, the plot file and optionally the dump file. The log file is a text file that contains the same output (and usually more) that was written to the screen. The plot file contains the results of the analysis. Since this is a binary file, the results must be analyzed using post processing software such as PostView. In some cases, the user may wish to request the creation of a dump file. This file contains temporary results of the run. If an analysis terminates unexpectedly or with an error, this file can be used to restart the analysis from the last converged time step. See Section 2.8.4↓ and Chapter 5↓ for more details. The names of these files can be specified with the command options –p (plot file), -a (dump file), -o (log file). If one or more of the file names following these flags are omitted, then the omitted file name(s) will be given a default name. The default file names are derived from the input file name. For example, if the input file name is input.feb the logfile will have the name input.log, the plot file is called input.xplt and the dump file is called input.dmp.
Note 1. The name of the log and plot file can also be specified in the FEBio input file. See Section 3.17↓ for more information.
Note 2. When running an optimization problem the name of the log file is derived from the optimization control file. See Chapter 7↓ for more information on running optimization problems with FEBio.
