Model problem 2, criss-cross triangulation

The iteration numbers of the MG and FMG method are presented in Table 9. Again the same conclusions as for the corresponding model problem 1 can be drawn. Table 10 comprises the degrees of freedom and the computational time for $\omega = 1.0$.

The strong dependence of the iteration numbers on the triangulation and the smoothing parameter $\omega$ is even more obvious for this model problem 2.
