Abstract
Efficient functional derivative formulas suitable for optimal discretizatio n; based refinement criteria are developed for 3-D adaptive finite element analysis (FEA) with scalar tetrahedra. Results for generalized scalar Poiss on and Helmholtz systems are derived directly from first principles, and co nfirmed numerically through fundamental benchmark evaluations. Practical ad aption applications are illustrated for selected FEA refinement models.
