How to build the optimal magnet assembly for magnetocaloric cooling: Structural optimization with isogeometric analysis

“…which is a saddle point problem as known from the literature (Egger et al, 2021). Here, the stiffness matrix 𝐊, the discrete solution vector for the magnetic vector potential 𝐮, and the contribution of the permanent magnets 𝐛 are separated on the domains 𝛺 rt and 𝛺 st .…”
