double oomph::HerschelBulkleyBerEngRegConstitutiveEquation< DIM >::dviscosity_dinvariant ( const double &  second_invariant_of_rate_of_strain_tensor)
inlinevirtual

Function returning the derivative of the viscosity w.r.t. the second invariant of the rate of strain tensor For Newtonian behaviour this returns 0.0

Implements oomph::GeneralisedNewtonianConstitutiveEquation< DIM >.
