One iteration of the linear system is just a blur which can be seen
from the bevel mode example pictures. When the change between iterations
drops below tolerance that's the solution for the Laplace equation.

That math book I mentioned only spoke about methods using linear systems
of equations and iteration. There may be other numerical methods geared
towards applications other than electrical engineering. Look for them using
laplace, poisson , differential, numerical.
