To configure a restart request:

1. From the main menu bar, select OutputRestart Requests.

   The Edit Restart Requests dialog box appears with a list of the steps in the current model.

2. From the dialog box, select the step and specify the frequency at which Abaqus writes restart information. Do the following:

   Abaqus/Standard and Abaqus/CFD

   For an Abaqus/Standard or Abaqus/CFD analysis step, enter the frequency in increments or in time intervals:

   • To write restart information after every regular number of increments, enter that number in the Frequency column.

   • To write restart information at a specific number of equally spaced time intervals during a step, enter that number in the Intervals column.

     Restart information is written at the increment ending immediately after the time specified by the time interval. In an Abaqus/Standard analysis, you can toggle on the Time Marks column to write restart information at the exact time specified by the time interval.

   By default, no restart information is written for an Abaqus/Standard or Abaqus/CFD analysis step (i.e., the frequency is set to zero).

   Abaqus/Explicit

   For an Abaqus/Explicit analysis step, enter the number of equally spaced time Intervals at which restart information is written. By default, Abaqus/Explicit writes restart information only at the beginning and end of each step (i.e., Intervals is set to one). You cannot avoid writing data to the restart files for an Abaqus/Explicit analysis step; the number of Intervals must be set to one or greater.

   By default, Abaqus/Explicit writes restart information at the increment ending immediately after the time specified by the time interval. Toggle on the Time Marks column to write restart information at the exact time specified by the time interval.

3. For an Abaqus/Standard or Abaqus/Explicit analysis, you can request that information from only one increment per step or from every specified increment be retained.

   • Toggle on the Overlay column to request that only information from one increment per step be retained in the restart files, thus minimizing the size of the files. When a step completes, the last increment is retained.

   • Toggle off the Overlay column to request that information from every specified increment or time interval be retained in the restart files.

   You can use the Overlay column only when the frequency is greater than zero.

4. Repeat Steps 2 and 3 for each step of the analysis.

5. When you have finished configuring your restart output requests, click OK to close the Edit Restart Requests dialog box.
