“…For FGMEE materials, we have (10) where u, Φ, and Ψ are the vectors of node displacement, node electrical potential, and node magnetic potential, respectively; N , N Φ , and N Ψ are displacement shape, electrical potential shape, and magnetic potential shape functions of ICS-FEM, respectively. N , N Φ , and N Ψ were expressed in similar shape functions.…”
