The beam dynamics code DYNAC* was originally developed at CERN. For accelerating elements a set of very accurate quasi-Liouvillian beam dynamics equations was introduced, applicable to protons, heavy ions and non-relativistic electrons. Furthermore, DYNAC contains three space charge routines, including a 3D version**. More recently, a numerical method has been added, capable of simulating a multi charge state ion beam in accelerating elements (i.e. cavities). Beam line devices such as sextupoles and quadrupole-sextupole magnets as well as electrostatic devices are now also included. Capability of second order calculations of such elements for a multi charge state beam has been implemented. Benchmarking of the code, in particular for a multi-charge state beam is discussed. Comparison of beam simulations results with beam measurements on the MSU ReAccelerator (ReA) are reported. The possibility of using DYNAC as an online tool for ReA and FRIB is discussed.
