Advanced Magnetics--Step-by-Step Description: Step 3
Creating geometry elements
First, we should make a decision concerning dimensions of the problem's region. We choose a region large enough to contain the outer rim of the motor, so the rectangle 50x50 mm will fit our region's geometry.
The first step with the new model in Model Editor is to adjust window dimensions fitting the problem's region. Due to the model's geometry, it is convenient to use the coordinate system with the origin at the center of the motor. So the region fits the square (-25 ≤ x ≤ 25, -25 ≤ y ≤ 25). To make this rectangle occupying most of the window:
-
Click Zoom In toolbar button.
-
Move mouse pointer to (-25, 25), checking the coordinates in lower right corner of the QuickField application window. You need not position mouse exactly at this point but somewhere to the bottom left not far the point.
-
Click the left mouse button and drag to (25, 25).
-
The window reflects your zoom operation. Click Zoom In once again co close zooming mode.
With this model, we'll use 0.5 mm grid to create the most of geometry elements and we'll use keyboard input to create precise elements that do not fit in 0.5 mm grid. To use Snap to Grid feature:
-
From Edit or context menu, click Grid Settings, a dialog box appears.
-
In Horizontal, type 0.5. Since Anisotropic box is unchecked, the same value appears in Vertical box.
-
Grid origin at (0, 0) is okay, so click OK to close the dialog.
