I'm a little bit confused about blending of schemes in code_saturne.
We can choose the second order scheme between Central & SOLU schemes by setting the value of ischcv to 1 or 0. I'm OK with these two choices.
We also have blencv which indicates the proportion of second-order convective scheme.
But there's another choice for ischcv and that is the number 3 which in doxygen we have:
Now the question is, if this option is about blending between two second-order schemes (Central & SOLU), then how can we set the blending percentage? By setting blencv? As doxygen says, blencv is blending between second-order and first-order schemes, not two second-order schemes.3: Blending between Second Order Linear Upwind and Centered scheme
Then if it is set by blencv or any other variables, the set value is for the proportion of Central scheme or SOLU scheme?
