[petsc-users] FEM Implementation of NS with SUPG Stabilization

[Brandon Denton]

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 residual calculations. How do I get these quantities at the quadrature points? The signatures for fo and f1 don't seem to contain this information.

Thank you in advance for your time.
Brandon
