UT for extrapolation.

The results can be analyzed visualy with gnuplot: if the output file is "out.dat", then use : plot "< cat out.dat | grep '^ *50 '" u 3:4 w lp, "< cat out.dat | grep '^ *56 '" u 3:4 w lp, "< cat out.dat | grep '^ *57 '" u 3:4 w lp, "< cat out.dat | grep '^ *58 '" u 3:4 w lp, "< cat out.dat | grep '^ *59 '" u 3:4 w lp

The spatial convergence can be analyzed visualy with gnuplot: plot x w l ls -1, 10*x**2 w l ls -1, 100*x**3 w l ls -1, 100*x**4 w l ls -1, "< cat out.dat | grep 'Error_o1_b'" u 2:3 w lp, "< cat out.dat | grep 'Error_o1_f'" u 2:3 w lp, "< cat out.dat | grep 'Error_o2_b'" u 2:3 w lp, "< cat out.dat | grep 'Error_o2_f'" u 2:3 w lp, "< cat out.dat | grep 'Error_o3_b'" u 2:3 w lp, "< cat out.dat | grep 'Error_o3_f'" u 2:3 w lp, "< cat out.dat | grep 'Error_o4_b'" u 2:3 w lp, "< cat out.dat | grep 'Error_o4_f'" u 2:3 w lp
