Abstract :
The existence of complementary energy bounds for magnetostatic problems discretized by the finite integration technique is proved, when material matrices are constructed according to the so-called energetic approach. A numerical example shows that complementarity provides fast and accurate estimates of global quantities such as the inductance.
