Finishing Relaxation

It is possible to start a dynamical run after relaxation finishes without starting the code. The parameter ``TRELOFF'' gives the time at which relaxation finishes, and if this is less than the time at which the run itself finishes, ``TF'', the code will switch to a dynamical mode, turning on the effects of AV and radiation reaction if the user indicated they should be used.

For a single star configuration the process is extremely simple. All velocities are set to zero and the run is relaunched. For the corotating binary case, All velocities are set such that

\begin{displaymath}
\vec{v}=\vec{\Omega}\times\vec{r},
\end{displaymath} (14)

where $\vec{\Omega}$ is taken to point in the z-direction. Note that this approach eliminates all spurious velocities which had yet to damp out.
