摘要
The flux density B for a magnetic field H in a soft magnetic material is given by the derivatives of the stored coenergy density with respect to the components of H. Any single-valued nonlinear tensor permeability may therefore be stored compactly, and retrieved with little computation, by storing its coenergy density as a function of position in H-space. In a dual form, H can be found by differentiating the stored energy density with respect to the components of B. Computational experiments show that sufficient accuracy can be achieved using cubic splines or other C2-continuous approximating functions.
