=== Advantages & Limitations of EM.Ferma's Static Simulator ===
EM.Ferma computes the electric and magnetic fields independent of each other based on electrostatic and magnetostatic approximations, respectively Static . These static or quasi-static approximations solutions are computationally much more efficient than the full-wave solutions of [[Maxwell's Equations|Maxwell's equations]] can be reliably applied in two different cases: at low frequencies from DC to a few Megahertz. Therefore, for low-frequency electromagnetic modeling problems or when the total electrical size for simulation of your physical structure is a fraction of the sub-wavelength and devices, EM.Ferma offers a faster alternative to [[EM.Cube]]'s full-wave retardation effects are negligiblemodules like [[EM. In the latter caseTempo]], your physical structure is effectively considered as a lumped device[[EM.Picasso]] or [[EM.Libera]].
