Abstract :
In this paper, an algorithm using mesh incidence matrices is developed for the fast generation of source magnetic fields. The mesh incidence matrices arise by applying cohomology concepts to the discrete form of the topological laws for source magnetic fields. The algorithm admits a unique and very fast integer Gaussian elimination procedure. The same algorithm is used to generate solenoidal current density in stranded conductors
