Hi, I am trying to implement vonNeumann and Ritchmyer's artificial viscosity for shock capture, which required a term delta^2, which is the center to center distance (or the vector(dx, dy, dz), the grid distance), how to obtain that with OpenFOAM's field operations?
Thanks a lot!
Hi Roy On patches the inver
On patches the inverse distance is found as this->patch().deltaCoeffs(). You might find something similar for the interior.
Otherwise, you need to locate owner/neighbour properties for each face and then calculate the distance by hand.
The shock capturing sounds very interesting.
P.S. Have seen a surfaceScalarField definition of deltaCoeffs at some point, but cannot recall where or when.
mesh.deltaCoeffs() will work.
mesh.deltaCoeffs() will work. It is in surfaceInterpolation.H.
