Hello VAMPIRE Users,
Can someone please explain with examples, the difference between chekpoint flags restart and continue. The documentation doesn't really describe what these two flags differently. To better explain my problem, I am trying understand the effect of domain wall motion in CrGeTe3. In order to simulate domain walls I am making 200x10 nm strip of CrGeTe3 with 100 nm spins up and down initially and run a time series for 50000 time steps at 1E-15 step. In order to equilibrate faster I set equilibration temperature at 0 K for 50000 equilibration steps and then total time steps 50000 at 10 K temperature. once the domain wall forms and equilibrates I would like to study the motion and its effect on ultrafast demagnetisation under thermal and magnetic pulse fields. Since pre pulse is not important for dynamics I seperate the equilibration routine and time dynamics routine. another reason to do this is equilibraton can be computed at critical damping = 1 since we dont care about dynamics there, therefore saving computation time. In this case, should I use checkpoint restart or continue as my checkpoint flag? in order to use the ending spin configuration in step 1 as starting point for step 2 ?
Thank You.

You probably want to use restart. However, you may read about the difference between restart and continue in the past post that should be at:
