corotating binary configuration with
equally-spaced particles
in both stars, you can use the
``setup2cs'' subroutine, which is called by setting the three
letter code in sph.init to ``2cs''.
The code lays down each star in an analogous manner to the equally-spaced
single star routines, and the same instructions about the relaxation
timescale and shutoff time apply.
Note that the parameter ``N'' used to initialize the run refers
to the approximate number of particles in EACH star, the total number
of particles will be approximately 
.
