Abstract
An approach based on the use of Thévenin-like conditions, in order to define a reduced domain for finite-element analysis (FEA), is proposed to help the solution of optimal synthesis problems in a cost-effective way. In particular, the mismatch of nodes discretizing the common boundary between reduced and complementary domain is considered. A case study in 2D magnetostatics, where the field domain is an open-boundary region, is considered.
