Thanks for the pointer, Vivek. I did check the usual locations, including fe_values.h, but couldn’t locate the exact implementation of the computation for the hessian in the real cell coordinates. (Should involve the product of shape function hessians in reference coordinates, and multiplication with a whole lot of inverse Jacobean terms.)
Still looking for its exact implementation ….. as I am curious about the computational cost of this implementation.
