step-21:
If the size of a linear system is small, i.e. when the mesh is very
coarse, then it is sometimes not sufficient to set a maximum of
<code>src.size()</code> CG iterations before the solver in the
<code>vmult()</code> function converges. (This is, of course, a result
of numerical round-off, since we know that on paper, the CG method
converges in at most <code>src.size()</code> steps.) As a consequence,
we set the maximum number of iterations equal to the maximum of the
size of the linear system and 200.

In the beginning the Universe was created. This has made a lot of people very angry and has been widely regarded as a bad move.
