GGU-CONTAM-RW: "Define concentrations individually" menu item

This menu item first generates a dialog box, in which you specify the font size and the number of decimal places. After confirmation you can click on nodes to which you want to assign an initial concentration (> 0.0) or a concentration source, using the left mouse button. A concentration source is constant over time.

Please ensure that you always use the same length and time units as those you applied to the permeability in the GGU-2D-SSFLOW steady-state modelling. You can define the mass dimension at will; you must, however, use the same dimension for all parameters. This also applies to soil properties.

If you click a node with the right mouse button, any initial concentrations existing at the node are deleted.
