Summary: Both continuous and discrete sensitivities and gradient evaluations carry important information in the building of an optimal shape loop. This is particularly true for the smoothness of objective functionals and the functions representing their gradients. The main application addressed here is the choice of a preconditioner for the optimisation loop.
