isvfrq=<integer> save=<filename>where ISVFRQ specifies the number of dynamics steps between updates of the restart file. Each time the restart file is updated, a new version of it is created.
To restart using an existing restart file, the following statement should be inserted immediately after the DYNAmics VERLet keywords:
restart=<filename>.The number of steps after a restart should be reduced, depending on how many steps were carried out before the restart. The recovery after a restart is complete; i.e., the trajectory is identical to one produced by a job without restarts. However, the restart file contains information only about the coordinates of the steps n-1, n, and n+1. All other structural information and databases have to be read again before executing the dynamics.
