7). 7. Background grid refinement: (a) generated surface points; (b) adjust background grid element size to surface point size; (c) refine background grid as required Pass 1: Background grid adjustment Suppose a background grid element has very large element sizes defined at its nodes. If it contains a generated point with characteristic length that is much smaller, an incompatibility is present. The aim of this first pass is to prevent these incompatibilities by comparing lengths. 16) sn (ci − 1) + δ1 .

Minimum element size from different surface sources The evaluation of the minimum distance obtained over the sources may be vectorized in a straightforward way. Nevertheless, a large number of sources (Ns > 100) will have a marked impact on CPU times, even on a vector machine. Experience shows that the large number of sources dictated by some complex geometries can lead to situations where the dominant CPU cost is given by the element-size evaluations of the sources, not the grid generation method itself.

3. E X 7. 9. Heap list: addition of entries Suppose the array to be ordered consists of nelem elements and is denoted by lelem(1:nelem) with associated keys relem(1:nelem). The positions of the son or the father in the heap list lheap(1:nelem) are denoted by ipson and ipfath, respectively. Accordingly, the element numbers of the son or the father in the lelem array are denoted by ieson and iefath. Then ieson=lheap(ipson) and iefath=lheap(ipfath). 9 one can see that the two sons of position ipfath are located at ipson1=2∗ipfath and ipson2=2*ipfath+1, respectively.
