Describing the field geometries (size, shape, and orientation).

Describe the simulation field geometry.

• Select the field dimensions.
• Click on the brown field shape in the center panel of the window.
• Click the 'Resize' button on the toolbar.
• Click and hold the left mouse button on the "handles" along the field border.
• Drag each border to obtain the desired field dimensions (ie. X-length, Y-length) as shown in the 'Simulation Region Info' box in the left panel.
• Select field orientation.
• Click on the 'Rotate' button on the toolbar at the top of the window.
• Using the mouse, rotate the field to the desired orientation.
• Click the left mouse button to 'fix' the field orientation.

Changing the field shape and orientation on the center panel screen were discussed above. Note that as these items are changed using the mouse to drag boundaries and orientation, the values are also changed in the 'Simulation Region Info' section in the left screen panel. The user may bypass using the mouse to drag the field boundaries and orientation by directly entering the information in the 'Simulation Region Info" box.
