PetscDualSpacePushforwardHessian#

Transform the given function Hessian so that it operates on real space, rather than the reference element. Operationally, this means that we map the function evaluations depending on continuity requirements of our finite element method.

Synopsis#

Input Parameters#

  • dsp - The PetscDualSpace

  • fegeom - The geometry for this cell

  • Nq - The number of function Hessian samples

  • Nc - The number of function components

  • pointEval - The function gradient values

Output Parameter#

  • pointEval - The transformed function Hessian values

Notes#

Functionals transform in a complementary way (pullback) to functions, so that the scalar product is invariant. The type of transform is dependent on the associated k-simplex from the DeRahm complex.

This only handles transformations when the embedding dimension of the geometry in fegeom is the same as the reference dimension.
