xisto Member Carlos Xisto Join Date: Nov 2009 Location: Covilhã, Portugal Posts: 53 Rep Power: 16	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? CX
