The way that Maxwell uses to compute the surface and volume force density, it is described in the Maxwell Help > Maxwell Coupling > Maxwell Harmonic Force Coupling > Force Density Calculation in Maxwell. In the link below you can find the documentation. https:\/\/ansyshelp.ansys.com\/account\/secured?returnurl=\/Views\/Secured\/Electronics\/v192\/home.htm%23..\/Subsystems\/Maxwell\/Content\/ForceDensityCalculationinMaxwell.htm?Highlight=Force%20density Fx,Fy, Fz are the force at the indicated direction (x, y , z). Mag Force = sqrt ( Fx^2 + Fy^2 + Fz^2 ) In cylindrical coordinate system, the force needs to be calculated using the Fields Calculator. In this case the direction is specified in Vector \/ Scal? \/ Scalar X In cylindrical the equivalence are: X -> Radial Y-> Phi Z -> Z The Mag Force is calculated using the equation described above, but based in the cylindrical CS.<\/p>\n","protected":false},"template":"","class_list":["post-164279","topic","type-topic","status-publish","hentry","topic-tag-19-2","topic-tag-electrical-machines","topic-tag-electromagnetics-electronics","topic-tag-force-torque","topic-tag-low-frequency-electromagnetics","topic-tag-maxwell","topic-tag-post-processing-maxwell"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
