A summary of activities that envisage a source to target simulation of the PSI cyclotron facility is presented. In the course of our ambitious high intensity upgrade, we aim to gain quantitative understanding of complex phenomena in our particle accelerators and beam lines. This ultimately leads to precise beam dynamics simulation. We discuss the implications of this undertaking with respect to physics and numerical models and highlight the importance of HPC. Examples will include three-dimensional space charge dominated beam transport in large structures and eigenmode calculations in large and complicated radio frequency cavities. Ideas for future development towards a time domain Maxwell solver for large structures will be presented.
