Electromagnetic Force Density in a Ferromagnetic Material

Computational electromagnetics for design optimisation: the state of the art and conjectures for the future

“…Unfortunately, the necessary gradient of the co-energy function is rarely available explicitly and thus at least two field solutions are needed, or even more to provide better accuracy. Ways of improving accuracy and reducing computational effort have been addressed by Coulomb [64], McFee [65] and Hameyer [66], amongst others. It is also worth highlighting a completely new force computation algorithm based on continuum design sensitivity analysis [67][68][69].…”

Some key developments in computational electromagnetics and their attribution

“…Variations of the two approaches have been considered by many authors in an attempt to improve the accuracy and reduce the computational effort. Of major note are the works of Coulomb [62], McFee [63], Kameari [64], and Hameyer et al [65]. A recent attempt is also worth mentioning of a force computation algorithm based on continuum design sensitivity analysis [66].…”

Field Simulation as an Aid to Machine Design: the State of the Art

“…However, the required gradient of the co-energy function is rarely available explicitly and thus at least two field solutions are needed, or more for better accuracy. Many researchers have addressed the problem of how to improve the accuracy and reduce the computational effort, and the reader is referred to the works of Coulomb [62], McFee [63] and Hameyer [64]. The most recent attempt is also worth highlighting of a force computation algorithm based on continuum design sensitivity analysis [65].…”
