walker::MixDirichletHydroTimeScale class

Contents

MixDirichlet coefficients policity: mean(rho) forced const in time

User-defined parameters b' and kappa' are functions of an externally, e.g., DNS-, provided hydrodynamics time scale ensuring decay in the evolution of <y_alpha^2>. Additionally, S_alpha is constrained to make d<rho>/dt = 0. Additionally, we pull in a hydrodynamic timescale from an external function.
