I don't see an attachment, but his thesis used conservative variables and
defined an effective length scale in a way that seemed to assume constant shape
function gradients. I'm not aware of systematic literature comparing the
covariant and contravariant length measures on anisotropic meshes,
I was thinking about trying to implement Ben Kirk's approach to Navier-Stokes
(see attached paper; Section 5). His approach uses these quantities to align
the orientation of the unstructured element/cell with the fluid velocity to
apply the stabilization/upwinding and to detect shocks.

Do you want to write a new code using only PETSc or would you be up for
collaborating on ceed-fluids, which is a high-performance compressible SUPG
solver based on DMPlex with good GPU support? It uses the metric to compute
covariant length for stabilization. We have YZƁ shock capturing, though
Good Evening,
I am looking to implement a form of Navier-Stokes with SUPG Stabilization and
shock capturing using PETSc's FEM infrastructure. In this implementation, I
need access to the cell's shape function gradients and natural coordinate
gradients for calculations within the point-wise
