Restarting From a Previous Run

If you are restarting directly from where a previous run stopped, the method is slightly different. Note that these instructions do not apply for taking a single-star configuration and using it as the basis for the components of a binary, see the sections above for more on this. To restart a run, take the required output file, in the form ``restart.sph'' or ``outxxx.sph', where ``xxx'' is a 3-digit integer, as described in Sec. 5.2.1, and rename the file ``restart.sph''. You will not need a file named ``sph.init'', as it will be ignored by the program if restart.sph is found. You will need a new version of sph.input as well. Most likely, you will want to adjust the parameter TF, the time at which the run ends, to increase the value. Other parameters can be changed, but be careful. We recommend you use the testinput routine the first time you try this to see how it works.
