follows we shall consider ®rst-order (linear) elements and the so-called h re®nement<br />

process in which increased accuracy is achieved by variation of element size. <strong>The</strong> p<br />

re®nement in which the order of the element polynomial expression is changed is of<br />

course possible. Many studies are available on hp re®nements where both h and p<br />

re®nements are carried out simultaneously. This has been widely studied by Oden<br />

et al. 32;33;51;52 but we believe that such re®nements impose many limitations on
