	A VUV-FEL operating over the photon energy range 3–10 eV is a component of the 4th Generation Light Source (4GLS) proposal by Daresbury Laboratory in the United Kingdom. This presentation gives an overview of the design of the 4GLS VUV-FEL, which is based on the concept of the Regenerative Amplifier FEL (RAFEL). A 3D optical propagation code which allows FEL codes such as Genesis 1.3 to be used in combination with full wavefront propagation through cavity elements has been developed at the University of Twente. This code has been used for initial transverse cavity mode analysis of the VUV-FEL and simulation results are presented in this contribution.
