To achieve this, and obtain the greatest efficiency, transfer lines will be based on electrostatic optics. Unfortunately, only a small amount of simulation codes allow realistic and flexible implementation of such elements. In this contribution, methods for accurately creating and tracking through electrostatic optical elements are presented, utilising a combination of finite element methods with both a modified version of G4Beamline and BMAD. A range of approaches to modelling the electrostatic elements were explored, ranging from simple field expressions, to the complex field maps used in the final model. An investigation into the achievable beam quality at one of the experiments is presented. Realistic beam distributions obtained via tracking around ELENA in the presence of collective effects and electron cooling will be propagated along the optimised 3D transfer lines models.
