=== Variety of Material and Source Objects ===
Your physical structure in EM.Ferma offers is typically made up of some kind of source either in the following types free space or in the presence of one or more material objects. EM.Ferma's electrostatic and magnetostatic simulation engines then discretize these source and material objects and solve the Laplace or Poisson equations to construct your physical structure for electrostatic find the electric or magnetostatic simulation:magnetic fields everywhere in the computational domain.
* Fixed-Potential Perfect Electric Conductor (PEC) Objects EM.Ferma offers the following types of material objects for construction of your physical structure:Â * Fixed-Potential Perfect Electric Conductor (PEC) Objects
* Dielectric/Magnetic Materials
 EM.Ferma also offers the following types of source objects for excitation of your physical structure: * Fixed-Potential PEC Objects with a Nonzero Voltage * Volume Charge Charges
* Wire Currents
* Volume Currents
* Permanent Magnets
All the CAD objects belonging to in the same group project workspace are organized together into object groups which share the same properties including color and electric or magnetic [[parameters]].
