6. Nodes and Elements

MINEDW provides comprehensive tools for selecting and manipulating nodes and elements within the finite-element mesh. These tools are essential for:

• Assigning and editing element properties (hydraulic conductivity, storage zones, recharge zones, evaporation zones)

• Assigning and editing node boundary conditions (constant heads, pumping wells, variable-flux boundary conditions)

• Moving nodes within the finite-element mesh

• Adding pinch-outs for increased vertical model discretization

• Refining and extending the mesh

This chapter covers the selection methods and operations available for both elements and nodes, including interactive selection tools, polygon-based selection, overlay-based selection, and property assignment dialogs.
