I am trying to add the following transport equation to rhoSimpleFoam:
Solve
(
fvm::ddt(rho,Z)
+ fvm:: div(phi,Z)
- fvm::laplacian(nuEff(),Z)
);

When I compile, I get the following error : "'nuEff() not declared in this scope "

How do I declare nuEff()?

[jherb]

nuEff is not defined in rhoSimpleFoam.C What should quantity should be stored in the field. In multiphaseEulerFoam/UEqns.H a nuEff is defined (see https://github.com/OpenFOAM/OpenFOAM...am/UEqns.H#L13) You have to add a similar definition to your code (of course depending on the physical meaning of your field)

Thank you for your answer. The piece of code compiles when modified as follows:

volScalarField nuEff( turbulence->nut() + turbulence-> nu());
