[[EM.Ferma]] is [[EM.Cube|EM.CUBE]]'s 3D static solver. It features two distinct electrostatic, and magnetostatic simulation engines that can be used to solve a variety of static and quasilow-static solverfrequency electromagnetic problems. Both simulation engines are based on finite difference solutions of Poisson's equation for electric and magnetic potentials.
With EM.Ferma, one can explore the fields in the vicinity of charge distributions, voltage sources, and current sources. Transmission line characteristic impedance (Z0) and Effective Epsilon can also be obtained.
