CUBISTA Scheme
 
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?

Thanks for your reply Alberto.

Here it is: http://webx.ubi.pt/~pjpo/ri29.pdf

Is the original paper regarding the CUBISTA scheme.

Hi xisto
you added CUBISTA scheme in openfoam.
can you help me for add this scheme?change gamma.c and gamma.H in openfoam?
please help me.

Did you implement the proposed scheme?

Hi,
did you implement CUBISTA scheme?
