How to Edit Initial Conditions

Initial Conditions can be specified in HYDRUS either

1. directly on the finite element mesh (as done in Version 1.0 and as described below), or

2. on geometrical objects (e.g., boundary curves, rectangles, circles, surfaces); see How to Define Properties on Geo Objects and Initial Conditions on Geo Objects.

How to Edit Initial Conditions on Finite Element Mesh

There are two ways how one can assign values of initial conditions (e.g., pressure heads, water contents, temperatures or concentrations) to selected nodes:

1. First select nodes (using either the mouse in the View Window, selecting geometrical objects on the Data Tab of the Navigator Bar, selecting Sections on the Section Tab of the Navigator Bar, or selecting objects by the mouse in the View Window and using the Ctrl keyboard button). Then after clicking on the Set Values button of the Edit Bar a dialog window appears in which one can specify required values.

2. One may also first click on the Set Values button of the Edit Bar, which will start the selection process. After the selection process of the FE-Mesh nodes by the mouse in the View Window is finished a dialog window will appear automatically in which one can specify required values
