Abstract

The field computation codes VEPO2 and POFEL3 have been developed and used extensively over the past decade for designing electric and electromagnetic devices for the cyclotron facilities currently under construction at the NAC near Cape Town [1]. In VEPO2 scalar or vector potential formulations and a rectangular mesh are used to solve linear and non-linear static field problems in two dimensions for various boundary conditions. Dirichlet boundary problems can be solved with POFEL3 for a scalar potential and polar mesh or cylindrical (r,θ,z) grid. Novel finite-difference representations and special concepts employed in these codes are presented and discussed together with various results obtained for typical applications.
