Detailed Description

Abstract interface for scattering a functional response's derivative back into global sensitivity vectors.

ResponseScatterEvaluator_Functional computes a scalar functional integral per cell; a FunctionalScatterBase implementation is responsible for taking that per-cell integral's derivative (with respect to local solution unknowns) and accumulating it into the appropriate entries of the response's global gradient (dgdx) or, if enabled, Hessian-vector product (d2gdx2).

pure virtual

Accumulates dg/dx contributions from one workset's cell integrals into the global gradient vector(s).

Parameters

cellIntegral	per-cell functional integral for this workset, carrying Jacobian (first-derivative) sensitivities.
workset	the workset being processed.
wda	accessor used to pull cell/block details out of `workset`.
dgdx	one global gradient vector per global indexer (block), to be accumulated into.

Implemented in panzer::FunctionalScatter< LO, GO >.
