To demonstrate the performance of the algorithm a realistic example is
presented. A spillway concrete dam (Fig. 4) has been
discretized using several control grids (with number of elements
ranging from 806 to 13.128). The resulting dependence of
the total computational time1 on the number of generated elements for
individual control meshes (see Fig. 5) approaches
computational complexity and
reveals only negligible sensitivity to the density of the control
grid (clearly caused by the last smoothing cycle with the enforced
``exact'' projection). The projection convergence criterion has been
set to 0.1 % of the local mesh size.
