Over the last years MAFIA has grown to a more and more universal design tool for a vast range of applications not only in the field of accelerator physics. The currently distributed version 3.1 now includes a new solver module for time harmonic fields that enables the computation of eddy current distributions as well as the fields in driven rf systems. MAFIA 3.1 also includes static modules for electric and magnetic fields, 2D and 3D resonator solvers, 2D and 3D time domain solvers as well as 2.5D and 3D PIC modules. Thus MAFIA 3.1 now virtually covers the entire range of electromagnetic field problems. The fully menu driven user interface has been enhanced by implementation of macros, symbolic variables, and language structures that makes MAFIA fully programmable. On the application side there are numerous highlights such as extremely fast and accurate computations of S‐parameters, calculation of antennas including farfield patterns, non‐destructive testing analysis for carbon fiber reinforced plastic as used as air plane material, etc., to name only a few. In the accelerator physics area the new version added many enhancements on the calculation of impedances and wake fields with the possibility to simulate very short bunches without excessive need for memory. Version 3.2, scheduled for release in fall 1993, contains further new features such as fully lossy materials (complex fields), cylindrical coordinates for better cavity design, a possibility to add user‐defined menus, various new 3D visualization tools, enhanced MAFIA language, and an AUTOMESH option. The most important new module is an optimizer, called OO, which basically combines all MAFIA modules into one (big) program. OO allows fully automatic optimization of electromagnetic components such as waveguide transitions, cavities, etc., according to user specified goal functions.
