A new unaveraged 3D parallelized numerical model has been developed that will allow investigation of previously unexplored FEL physics. Unaveraged models are required to describe such effects as amplification of Coherent Spontaneous Emission and non-localised electron dynamics (see e.g. [1] and refs therein). A previous parallelized 3D model [2] was based upon a mixed finite element/Fourier method, however, there were some limitations in the parallel algorithm and numerical routines. These limitations are removed in the new model presented here by using only transforms in Fourier space enabling more effective data or-ganization across multiple parallel processors and therefore allowing larger, more complex FEL systems to be studied. Furthermore, unlike the previous 3D model, which uses commercial numerical packages, the new simulation code uses only open-source routines.
