/*! @brief class Fluide_Ostwald
 *
 *  Has the properties of an incompressible fluid plus:
 *  N: structure index
 *  K: fluid consistency
 *  The dynamic viscosity in this case depends on K, N and Grad(U).
 *  A new fluid: it is a non-Newtonian incompressible fluid. It therefore derives
 *    from Fluide_Incompressible and has a few additional properties (K, N).
 *    mu depends on K, N, and grad(U).
