tion, they allow a local mesh refinement around the
point, and they can be used for parameter assignment,
e.g., to set the boundary condition for a pumping well.

Sets of polygons have to fulfil some requirements:
• No overlapping polygons are allowed.
• No polygons can be entirely contained by another
polygon.
The user-interface tools ensure that these requirements
are met at any time. Internal holes in the supermesh
are possible. They are indicated by another color
for the internal boundary (Figure 5.2).

The Mesh-Editor toolbar provides the tools to digitize
and edit Supermesh polygons, lines, and points.
In Move Node mode, both the originally digitized
nodes and smaller nodes in between can be moved.
Moving the small nodes results in curved polygon
edges (parabolic or circular shape) that are typically
applied to curved structures such as borehole edges or
pipe walls in small-scale models.
When digitizing a polygon next to an existing one,
the editor will automatically follow the existing polygon
boundary to close the new polygon (Figure 5.3).
