Multidisciplinary Optimization Formulation for the Optimization of Multirate Systems [PDF]
IEEE Transactions on Magnetics, 2016 Multidisciplinary optimization strategies are widely used in the static case and can be extended to a problem with a time-domain model in order to reduce optimization time. The waveform relaxation method is a fixed-point approach applied to waveforms, which allows the coupling of dynamic models. Using the individual discipline feasibility strategy, the
