Hi, I want to extend the kOmegaSST model by a term modifying the omega equation near the interface of a two-phase liquid gas flow in interFoam.
For this I need the gradient of the alpha_ field.
In order to calculate the gradient in the correct() function of the turbulence model
I need a volScalarField of alpha but alpha is of type alphaField. The stupid Idea
of const volScalarField& alpha = alpha_ ; do not work.
Have anybody a Idee how to get the gradient of a alphaField?

Thanks

I fond the solution:
const immiscibleIncompressibleTwoPhaseMixture& mixture = refCast<const immiscibleIncompressibleTwoPhaseMixture>(this->transport()) ;
const volScalarField& alpha1 = mixture.alpha1();
Thanks
