  A Geant4 simulation code was developed to perform realistic simulations of
the RIBRAS facility. A second order expansion of a finite solenoid field was
included to describe the beam optics with a good precision. A systematic study
of coil currents for several magnetic rigidities and focal points was
performed. Parameterizations of the coil currents for single and dual mode
operations were obtained. Dedicated routines were developed to simulate the
mechanism of direct reactions involving two and three particles in the final
state. The present simulations were employed to investigate the feasibility of
a Solenoidal Spectrometer with the RIBRAS facility. Our first results indicate
that the concept can be applied in the RIBRAS system under certain conditions.
Forthcoming studies both from simulations and experiment are already under
development.
