2.5 Axisymmetric Surfaces
In the subroutines that solve axisymmetric Laplace problems
the boundaries must
be represented in the form of a set of truncated cone shells.
In axisymmetric problems the surface can be defined
by specifying the points on the generator and
sweeping through 2p.
In order that the normal to the boundary points outward rather
than inward the two nodes that define each element must
be listed in the clockwise direction around the generator
of the boundary.
each solve Laplace
problems in which the boundary under consideration is that of
a sphere of unit radius.
