I am currently working in my PhD using OpenFOAM.

Currently I'm trying to implement the CUBISTA scheme (see attachment) in openFoam which is a limited scheme.

However I have some doubts.

Looking at the paper regarding the Gamma scheme, I understand where (in OpenFOAM) is calculated the phict (Eq.22) (NVDTVD.H), and the blending factor (Eq.21) (Gamma.H).

What I do not understand is where is calculate the value in the face, based on the value of the \phi c tilde, for the UDS, CDS or Blending?

Anyone knows how the steps to implement a new differencing scheme?
