+ +We see that, as expected, on each refinement step the two solutions +coincide. The difference measured in time of treating each face only +once (second version of the DG method) in comparison with treating +each face twice within a nested loop over all cells and all faces of +each cell (first version), is much less than one might have +expected. The gain is less than 20% on all refinement steps. +

+ +

First we show the solutions on the initial mesh, the mesh after two +and after five adaptive refinement steps. +

+ sol-0.gnuplot + sol-2.gnuplot + sol-5.gnuplot +

+ +

And finally we show the final grid (after 5 refinement steps). The +grid is largely concentrated in the vicinity of the jump of the +solution. +

+ grid-5.eps +
