Abstract

The topology optimization of nonlinear magnetostatic systems is studied using the finite-element method. The topology design sensitivity formulation of nonlinear magnetostatics is derived using the adjoint variable method. A computer program is developed using object-orient programming and applied to the topology optimization of a C-core actuator. A numerical study shows the effect of saturation by comparing linear and nonlinear topology optimization
