At the end of an electrostatic simulation, the electric field vector and electric scalar potential values are computed at all the mesh grid points of the entire computational domain. At the end of an magnetostatic simulation, the magnetic field vector and magnetic vector potential values are computed at all the grid nodes. Besides the electric and magnetic fields, EM.Ferma can compute a number of field integral quantities such as voltage, current, flux, energy, etc. The field and components, potential values and field integrals are written into output data files and can be visualized on the screen or graphed in EM.Grid only if you define a field sensor or a field integral observable. In the absence of a defined any observabledefined in the navigation tree, the static simulation will be carried out and completed, but to action no output simulation data will take placebe generated.

The Field Sensor dialog allows the user to select the direction of the sensor (X, Y, Z), visualization type, and whether E-field output or H-field output will be shown during a sweep analysis. The E-fields and H-fields are computed at each mesh node within the specified 2D Field Sensor plane. In other words, the resolution of the Field Sensor is controlled by the mesh resolution.| None|}
