Hi all, I was just wondering whether OF SFCD convection scheme was suitable for tetrahedral meshes or not.
Thank you a lot for your always appreciated suggestions
Cosimo

Not sure what you mean by "suitable". SFCD (Self-Filtered Central Differencing) is quite an old scheme with a pretty obscure reference (does anyone apart from me actually know it?) and there is nothing special in it. When I implemented it originally about 12 years ago, I used the unstructured mesh trick described in the Gamma scheme paper.

In short, yes it will work, no there is nothing tet-specifc in the scheme and yes there are much better choices for convection discretisation in OpenFOAM.

Thanks a lot Hvroje,
with suitable I meant what you exactly guess: if it was implemented in a way supporting arbitrarly shaped mesh as in the Gamma paper.
Thank you again
Cosimo
