GGU-2D-SSFLOW: "Point sources" menu item

Using this menu items source boundary conditions are defined within the FEM system in analogy to the displacement boundary conditions. A source is positive if it brings water into the system.

ATTENTION:
When calculating axis-symmetrical groundwater flow these sources are multiplied internally with 2··r, so that no intervention by the user is needed in the running of the program.

Note on impermeable boundaries:
The case of an impermeable boundary is automatically considered by the finite-element-method. Valid is, that all system boundaries or partial boundaries which have no water level or source boundary conditions, are automatically impermeable.

After clicking the "Graphically" button the FEM mesh is displayed with any existing sources. You can define a source boundary condition at the FEM nodes using the left mouse button, or edit existing sources. A right-click deletes existing sources.

After clicking the "Table" button the same dialog box opens as for the "Boundary/Individual potentials" menu item. You can edit the source values for various nodes, convert sources to potentials or delete sources.
