A 3D computer code for steady-state magnetic field calculation in air

A 3-D computer code for the calculation of magnetic fields, self- and mutual-inductance coefficients, and electromagnetic forces is considered. A unique feature of this code is the presence of a number of very precise models for the calculation of the field produced by circular or noncircular coils, busbars, or any other kind of conductor of arbitrary shape. The possibility of using different coordinate systems for input/output data represents an additional user-oriented facility. The problems of singularities both for the elliptic integral calculation, used for circular coils, and for Biot-Savart´s integral have been taken into account for the field calculation inside the conductors. Since this code has been conceived to solve magnetostatic problems in air-core devices for fusion research, an easy input for particular windings, such as toroidal and poloidal windings, is also provided. A means for automatic generation of the points of the current lines in busbars and in noncircular coils has been inserted in the code as well
