Solution: The calculations are performed to investigate the mechanical torque (per 1 m depth) in the function of the cover thickness and the current density (also other characteristics of materials). You can observe the saturation effect of the mechanical torque with the steel cover growth and a deformation of the field lines with the current density growth. This information can be useful in a design process. Results: View simulation report in PDF. Download simulation files (files may be viewed using any QuickField Edition). There are no restrictions applied to the QuickField Student Edition postprocessors. You can view field maps, make plots, calculate integrals and print pictures in the same way that the Professional Edition users do.
