mesh generation and solution procedures and as most ¯uid mechanics problems<br />

involve an explicit time marching algorithm, the higher-order elements are not<br />

popular.<br />

<strong>The</strong> determination of error indicators in linear elements is achieved by consideration<br />

of the so-called interpolation error. Thus if we take a one-dimensional element of<br />

length h and a scalar function , it is clear that the error in is of order O…h 2 † and that
