MAFIA - a three-dimensional electromagnetic CAD system for magnets, RF structures, and transient wake-field calculations

The acronym MAFIA stands for the solution of Maxwell's equations by the finite integration algorithm, and is the name given to a set of codes intended for use in the computer-aided design of three-dimensional magnets, rf structures, and structures in which wake-field effects are important. The interconnection of the various codes in the MAFIA collection are shown. M3 is the mesh generator used by all the MAFIA codes, T3 is the wake-field code, R3 generates the matrix whose eigenvalues and eigenvectors yield the frequencies and electric field components, receptively, of the normal modes of electromagnetic oscillations of an rf structure, E3 is the eigenvalue solver, and P3 is the postprocessor that calculates the quantities of physical interest, such as shunt impedance, quality factor, deflection integrals, etc. The code S3, now being written will solve electro- and magnetostatic problems. The collection of programs M3, R3, E3, and P3 are also known as URMEL-3D. A description of the FIT method is given, followed by brief descriptions of the codes M3, R3, E3, and P3. Finally, how one can get and use these codes are discussed
