  The RAON accelerator of the Rare Isotope Science Project (RISP) has been
developed to create and accelerate various kinds of stable heavy ion beams and
rare isotope beams for a wide range of the science applications. In the RAON
accelerator, the rare isotope beams generated by the Isotope Separation On-Line
(ISOL) system will be transported through the post accelerator, namely, from
the post Low Energy Beam Transport (LEBT) system and the post Radio Frequency
Quadrupole (RFQ) to the superconducting linac (SCL3). The accelerated beams
will be put to use in the low energy experimental hall or accelerated again by
the superconducting linac (SCL2) in order to be used in the high energy
experimental hall. In this paper, we will describe the results of the
start-to-end simulations with the rare isotope beams generated by the ISOL
system in the post accelerator of the RAON accelerator. In addition, the error
analysis and correction at the superconducting linac SCL3 will be presented.
