An analogy between open boundary condition and infinite element domains

Affifa Adeeb¹, Timothy J Flack¹
¹University of Cambridge, Cambridge, United Kingdom

A magnetic field associated with current carrying coil(s) extends towards infinity, but an analytical model is of finite size. In the finite element analysis (FEA) of electromagnetic systems, open space needs to be modelled as close to reality as possible to get reliable results without ... En savoir plus
