Step 1: Start

This step sets up the flow domain, mesh, and average hydraulic gradient.

• Click the "Start" button to bring up the Start Dialog Box.
• Enter the size of a square element, number of rows and column, and average hydraulic gradient. For example, if the element size is 10 m, and there are 40 columns and 20 rows, the grid will be 400 m by 200 m.
• Click "OK".

The program generates a rectangular mesh and then splits each square element into two triangular elements.
