ABAQUS 2016

Checkpointing and restart

Users sometimes find that their jobs take longer than the maximaum runtime permitted by the scheduler to complete. Providing that your model does not automatically re-mesh (for example, after a fracture), you may be able to make use of Abaqus’ built-in checkpointing function.

This will create a restart file (.res file extension) from which a job that is killed can be restarted.

  1. Activate the restart feature by adding the line:
*restart, write

at the top of your input file and run your job as normal. It should produce a restart file with a .res file extension.

  1. Run the restart analysis with

abaqus job=jobName oldjob=oldjobName ...

where oldJobName is the initial input file and newJobName is a file which contains only the line:

*restart, read

Example:

INPUT: dynam.inp

JOB SCRIPT: job.sh

INPUT FOR RESTART: dynamr.inp
