Default Changing Viscosity in solver

Hi all,
I am working on the viscosity value in a multiphase solver. Due to some modifications, I need to change the viscosity value in the solver using a function in my defined class. So I used the following line to access the viscosity and change it.


Code:
volScalarField k_viscosity = turbulence->nu();
particleCloud.setParticleViscosity(k_viscosity);

However, by these lines, only the k_viscosity value is changed using call by reference in setParticleViscosity function. So how can give the modified k_viscosity to nu? I think that's a big question I couldn't find its answer.
Cheers,

Mohammad

Finally solved the problem by myself using a function, correctnu, like correct(), to update the viscosity in each time step.
