In applications solutions of systems of hyperbolic balance laws often
have to satisfy additional side conditions. We consider initial value
problems for the general class of Friedrichs systems where the solutions
are constrained by differential conditions given in the form of
involutions. These occur in particular in electrodynamics, electro- and
magnetohydrodynamics as well as in elastodynamics. Neglecting the
involution on the discrete level typically leads to instabilities. To
overcome this problem in electrodynamical applications it has been
suggested in Munz et al. (2000) to solve an extended system. Here we
suggest an extended formulation to the general class of constrained
Friedrichs systems. It is proven for explicit Finite-Volume schemes that
the discrete solution of the extended system converges to the weak
solution of the original system for vanishing discretization and
extension parameter under appropriate scalings. Moreover we show that
the involution is weakly satisfied in the limit. The proofs rely on a
reformulation of the extension as a relaxation-type approximation and
careful use of the convergence theory for finite-volume methods for
systems of Friedrichs type. Numerical experiments illustrate Off
analytical results. (C) 2015 Elsevier Inc. All rights reserved.

%X In applications solutions of systems of hyperbolic balance laws often
have to satisfy additional side conditions. We consider initial value
problems for the general class of Friedrichs systems where the solutions
are constrained by differential conditions given in the form of
involutions. These occur in particular in electrodynamics, electro- and
magnetohydrodynamics as well as in elastodynamics. Neglecting the
involution on the discrete level typically leads to instabilities. To
overcome this problem in electrodynamical applications it has been

Friedrichs systems. It is proven for explicit Finite-Volume schemes that
the discrete solution of the extended system converges to the weak
