We describe the PC based computer program CAGEN in its current state of development. It models the performance of many varieties of magneto-cumulative-generators (MCG) which are energized with high explosive (HE). CAGEN models helical or coaxial types (in the same generator, if desired) which have HE on the interior. Any materials and any HE types may be used. The cylindrical radius of the windings (or outer conductor) and the radius of the armature may vary with axial position. Variable winding width, thickness, shape, and pitch can be represented, and divided windings are allowed. The MHD equations are used to advance the magnetic field into and through the conductors in order to compute resistance, melting, flux loss, pressure and contact effects. The MCG model is treated as part of a lumped circuit, which includes the priming circuit, several different opening fuse switches, transformers, peaking circuit, and loads. Several calculations of benchmark published experiments are shown. A typical problem will complete in a few minutes. Graphical input, run control, and results-analysis, is provided by MathGraf, a CARE'N CO. application.
