Hello everyone,

I need a help regarding the clarification of the order of accuracy and if possible mathematical implementation differences between faceCorrected and Corrected surface normal gradient scheme ?

I am finding the face corrected scheme more stable than the latter.

For complete description of the case and result, please refer this

Difference between faceCorrected and corrected surface normal gradient schemes

Thanks for your time.

Edit:
The links for schemes:
faceCorrected - https://github.com/OpenFOAM/OpenFOAM...orrectedSnGrad

corrected -
https://github.com/OpenFOAM/OpenFOAM...orrectedSnGrad

Best regards.

hello, have you find the difference. It seems the face gradient is recomputed by the node value, not by interpolation.
