By default, no restart information is written for an Abaqus/Standard analysis and restart information is written only at the beginning and end of each step for an Abaqus/Explicit analysis. However, default restart requests are created automatically for every step in an analysis. The Edit Restart Requests dialog box, invoked by selecting from the main menu bar in the Step module, allows you to specify how often you want the restart information to be written. You can specify the frequency at which Abaqus writes data to the restart files; however, the behavior of restart differs between analysis products.
For an Abaqus/Standard or an Abaqus/Explicit analysis, you can request that data written to the restart files overlay data from the previous increment. If you select this option, Abaqus retains the information from only one increment of each step in the restart files, thus minimizing the size of the files. By default, Abaqus does not overlay data. For more information, see Restarting an analysis, and Restarting an Analysis. For detailed instructions on requesting restart output, see Configuring restart output requests. You can use the abaqus restartjoin execution procedure to extract data from the output database created by a restart analysis and append the data to a second output database. For more information, see Joining Output Database (.odb) Files from Restarted Analyses. |
