Restart write

**Restart write

With this option a restart file is written at the end of the step in which this keyword is written (Restart write has to be specified in the step environment). The Restart write command generates all necessary files to restart the analysis using the Restart read command (see below).

Restart read

**Restart read, step = <step number>

With this option a restart of a previous calculation is performed. The new analysis starts after the step number specified with <step number>. Note that the restart files have to be written beforehand in the specified step using the Restart write command. The input file specified in the restart analysis has to define the complete database the previous job has used and has to contain the same number of steps the original job had. Technically, the exact same input file can be used again with the addition of the Restart read command. It is also possible to redefine the model (e.g. change material properties). However, the same mesh has to be used.

The restart analysis has to be specified in the command line using oldjob=<old job name>, where <old job name> is the job name of the analysis the restart is performed for.
