1) Write on initial input file
*RESTART, WRITE, FREQ=999, OVERLAY
2) Write on restart input file
*RESTART, READ, STEP=2, INC=10, END STEP, WRITE, OVERLAY
This Option specifies that the analysis is continued from Step 2, increment 10.
The END STEP parameter terminates the current step at this point.
If this parameter is omitted, the 10 increment default limit for the step will again prevent the analysis from continuing.
The WRITE parameter writes restart output at the default frequency of 1(every increment).
The OVERLAY parameter causes restart data from each increment to overwrite data from the previous increment so that only last increment is retained.
