outfile : filename for NetCDF output dt : time interval for the integrator nout : frequency of data outputs NOTE for GSL integrator (non-Brownian), this is just an initial one, for non-zero Stokes, "dt" is the upper limit, for zero Stokes, "dt * nout" is the upper limit, for Brownian, "dt" is fixed by this value. nloop : number of output steps (time duration is "dt*nout*nloop") flag-Q : #t output quaternion, : #f no quaternion in the output.
