[killsecond]

Hi all,
I want to use the function trunc() in my turbulence model, its' type is "double trunc(double)", but I want to Implement it as "trunc(k_)" and the k_ is "volScalarField" type, so something went wrong when I compiled:

error: cannot convert ‘Foam::tmp<Foam::GeometricField<double, Foam::fvPatchField, Foam::volMesh> >’ to ‘double’ for argument ‘1’ to ‘double trunc(double)’

How can I solve this problem? Thank you!
