A new constrained formulation of the Maxwell system. (English) Zbl 0874.65097
The authors present a new constrained formulation of the Maxwell equations in order to improve the numerical verification of the divergence relations $$\roman {div} \;\mathbf B = 0, \;\text{div} \;\mathbf E = \frac{\varrho}{\epsilon_0}$$. The stability of the finite volume schemes applied to the new constrained system using rectangular and triangular meshes is also studied. The authors present some numerical results in order to demonstrate the efficiency of this method.
