A. Patra et Jt. Oden, COMPUTATIONAL TECHNIQUES FOR ADAPTIVE HP FINITE-ELEMENT METHODS, Finite elements in analysis and design, 25(1-2), 1997, pp. 27-39
In this paper we present some new computational techniques designed fo
r adaptive hp methods. We also list some established and successful te
chniques. In particular we introduce a new robust solver for such meth
ods using a novel ''space-filling curve'' based ordering of the unknow
ns and a multilevel substructuring type factorization. We also outline
an a posteriori error estimator that can be easily used in conjunctio
n with this solver. The ordering introduced is of general applicabilit
y and can also be used with non-adaptive methods to great advantage.
